So, which machine makes more sense for your sewing requirements?

This Singer M3330 vs Brother GS3700 comparison breaks down their features, usability, dressmaking capabilities and ideal applications so you can make an informed choice.

Singer M3330 vs Brother GS3700: Quick Comparison

Both machines are intended for portable home sewing rather than continuous industrial production.

Understanding the Singer M3330 and Brother GS3700

Although both belong to the mechanical sewing machine category, their feature sets make them attractive to different users.

Singer M3330: Straightforward Motorised Sewing

The Singer M3330 Motorised Sewing Machine is designed for users who want mechanical controls with useful functions for everyday home and garment sewing.

Its 70W motor provides motorised operation, with sewing speeds reaching up to 800 stitches per minute.

The M3330 also provides a 1-step buttonhole, making buttonhole creation more convenient when working on garments such as shirts, dresses and kurtis.

Variable stitch width of up to 5 mm provides additional control over applicable stitches, while a thread cutter located on the faceplate makes it convenient to trim thread after sewing.

For users who primarily want straightforward garment stitching, alterations, repairs and creative home sewing without complicated electronic controls, the M3330 provides a practical mechanical option.

Brother GS3700: More Stitch Variety and Creative Control

The Brother GS3700 Sewing Machine takes a broader approach to mechanical home sewing.

It provides 37 built-in stitches and 71 stitch functions, giving users numerous options for everyday sewing, dressmaking and decorative projects.

The machine can sew at speeds of up to 800 stitches per minute, matching the maximum rated speed of the Singer M3330.

One of its notable advantages is the ability to independently control stitch dimensions. The GS3700 provides a maximum stitch width of 5 mm and maximum stitch length of 4 mm.

It also includes an automatic needle threader, horizontal quick-set bobbin, LED sewing light, free-arm capability and a 1-step automatic buttonhole.

For users who expect to explore a broader range of sewing techniques, these additional functions can provide greater flexibility.

Singer M3330 vs Brother GS3700: Detailed Comparison

1. Stitch Variety

One of the clearest differences between these machines is stitch selection.

The Brother GS3700 provides 37 built-in stitches and 71 stitch functions. This gives users a broad selection for garment construction, decorative stitching and creative home sewing.

The Singer M3330 provides multiple stitch options and sewing applications suitable for everyday home and garment sewing.

However, stitch count should not be viewed in isolation.

A home user who primarily performs alterations, repairs and basic garment stitching may rely on only a handful of stitches regularly. Someone interested in creative dressmaking may find a broader stitch library more useful.

Think about the stitches you will actually use rather than simply choosing the machine with the larger number.

2. Sewing Speed

Both the Singer M3330 and Brother GS3700 can reach maximum sewing speeds of approximately 800 stitches per minute.

For regular home sewing, this provides enough speed for many common garment and household projects.

Beginners should remember that maximum speed is not necessarily something they need to use immediately.

Good fabric control and accurate stitching are more important than sewing as quickly as possible.

As skills develop, having additional speed available can make longer seams and larger projects more efficient.

3. Stitch Length and Width Control

Stitch adjustment is particularly useful for users who want more control over the appearance and function of their stitches.

The Singer M3330 provides variable stitch width up to 5 mm.

The Brother GS3700 provides independent stitch length and width controls, with stitch width up to 5 mm and stitch length up to 4 mm.

These controls allow users to adapt compatible stitches according to the garment, fabric and sewing technique.

For someone learning more advanced garment construction or creative sewing, understanding stitch length and width becomes increasingly valuable.

4. Buttonhole Function

Both machines provide a 1-step buttonhole.

This is an important convenience for dressmaking.

On more basic machines, users may need to complete buttonholes through several separate stages. A 1-step function simplifies the process and makes repeated buttonhole sewing more convenient.

If you regularly make shirts, kurtis, dresses or other garments requiring buttons, either machine provides a useful advantage over basic 4-step buttonhole models.

5. Needle Threading

The Brother GS3700 includes an automatic needle threader.

This helps guide the thread through the needle and reduces one of the small repetitive tasks involved in preparing the machine.

For someone who sews frequently, convenience features like this can make regular operation more comfortable.

When comparing machines, these smaller usability features can matter just as much as headline specifications.

6. Bobbin System

The Brother GS3700 uses a horizontal quick-set bobbin system.

The bobbin can be accessed from the top of the machine, helping make bobbin preparation and replacement convenient.

For beginners, an easily accessible bobbin system can make learning machine setup less intimidating.

Whatever machine you choose, understanding how to correctly wind, insert and thread the bobbin remains an essential sewing skill.

7. Garment Sewing

Both machines can be used for home garment construction.

The Singer M3330 provides useful functions for everyday garment stitching, alterations, repairs and buttonhole creation.

The Brother GS3700 adds a larger selection of stitches, adjustable stitch dimensions and free-arm capability.

Free-arm sewing is particularly useful for cylindrical garment areas such as:

• Sleeves
• Cuffs
• Trouser hems
• Children’s garments
• Other narrow tubular sections

If garment making is a major reason for purchasing a sewing machine, consider how frequently you will use these functions.

8. Decorative and Creative Sewing

The Brother GS3700’s 37 built-in stitches and 71 stitch functions provide substantial variety for users interested in creative home sewing.

This makes it useful for people who enjoy experimenting with decorative details in addition to regular garment construction.

The Singer M3330 can also handle creative sewing applications, but its appeal is more strongly centred around straightforward mechanical garment and home sewing.

If decorative sewing will be only an occasional requirement, you may not need a large stitch library.

If it is an important part of your hobby, broader stitch selection becomes more relevant.

9. Ease of Use

Both machines retain mechanical operation.

This means you don’t need to navigate an LCD screen or complicated computerized interface to select everyday functions.

For many beginners, this can make the learning process easier.

The Brother GS3700 adds convenience features such as automatic needle threading and quick-set bobbin loading, while the Singer M3330 provides straightforward physical controls.

The easier machine for you may simply be the one whose controls you find more intuitive when you actually use it.

10. Portability

Both machines are designed as portable mechanical sewing machines.

This makes them convenient for users who don’t have a permanent sewing workspace.

They can be set up on a suitable table when required and stored after sewing.

This is particularly useful for:

• Apartment users
• Students
• Occasional sewists
• Home dressmakers
• Users with limited workspace

Portability is one of the major reasons these machines are more appropriate for home use than large industrial models.

Singer M3330 vs Brother GS3700 for Beginners

Both machines can be considered by beginners.

The Singer M3330 offers mechanical operation with useful functions for learning everyday garment sewing.

The Brother GS3700 also uses mechanical controls but provides additional stitch variety and convenience features.

A complete beginner should not assume that more stitches automatically make a machine easier to learn.

Start by mastering:

• Machine threading
• Bobbin preparation
• Straight stitching
• Fabric control
• Seam allowances
• Zig-zag sewing
• Stitch length and width
• Basic buttonholes

Once these fundamentals become comfortable, additional stitch patterns become much more useful.

Singer M3330 vs Brother GS3700 for Dressmaking

Dressmaking is where feature differences can become more noticeable.

Both machines can handle common garment-sewing applications, but users interested in experimenting with more stitch types may appreciate the GS3700’s broader stitch selection.

Its adjustable stitch length and width, free-arm sewing and automatic needle threading also provide useful convenience during regular garment work.

The Singer M3330 remains a practical option for straightforward dressmaking, alterations and everyday sewing where advanced stitch variety isn’t the primary requirement.

Before choosing, think about whether you plan to make complete garments regularly or mainly handle occasional alterations and repairs.

Which Machine Is Better for Home Tailoring?

Home tailoring requirements vary considerably.

Someone stitching occasionally for family members may need only essential functions. Another person may be handling regular alteration orders or creating custom garments from home.

Both machines can support regular home sewing.

However, if your workload becomes continuous and commercially demanding, the more important question may eventually become whether you should move from a portable machine to an industrial sewing machine.

Portable mechanical machines are designed differently from machines intended for long production cycles.

Choose based on workload rather than simply assuming a feature-rich home machine can replace an industrial machine.

Singer vs Brother: Should Brand Decide Your Choice?

Singer and Brother are both established sewing machine manufacturers, but choosing between these two models should not be based only on the logo printed on the machine.

Instead, compare:

• Stitch options
• Sewing applications
• Ease of threading
• Bobbin system
• Buttonhole functionality
• Stitch adjustments
• Sewing frequency
• Service requirements
• Current price
• Availability

A model that fits your actual sewing requirements is more useful than choosing solely because you are familiar with one brand.

Singer M3330 vs Brother GS3700: Which Should You Choose?

The best choice depends on what you intend to sew.

Consider the Singer M3330 if:

• You want straightforward mechanical operation.
• You primarily need everyday home sewing.
• Garment alterations and repairs are important.
• You want sewing speeds up to 800 SPM.
• You need a 1-step buttonhole.
• You want variable stitch width.
• You prefer practical functionality without focusing heavily on a large stitch library.

Consider the Brother GS3700 if:

• You want 37 built-in stitches and 71 stitch functions.
• You are interested in dressmaking and creative sewing.
• You want adjustable stitch length and width.
• You want an automatic needle threader.
• You prefer a horizontal quick-set bobbin.
• You want free-arm sewing.
• You want a 1-step automatic buttonhole.
• You expect to explore more sewing techniques as your skills develop.

Neither machine should be selected simply because it has a higher number beside one specification. The machine should match your actual sewing habits.

What Should You Check Before Buying?

Your Main Sewing Purpose

Decide whether your machine will primarily be used for repairs, alterations, complete garment construction or creative projects.

Your Experience Level

Beginners benefit from straightforward controls, but choosing a machine with some room for skill development can also be worthwhile.

Stitch Requirements

Consider which stitches you genuinely expect to use instead of focusing only on the total stitch count.

Frequency of Sewing

A machine used twice a month has different requirements from one used several hours every day.

Future Requirements

If sewing may develop into a tailoring business, think about whether you will eventually need an industrial machine alongside your portable model.

Service Support

Access to product guidance and service support should form part of the purchasing decision, especially if this is your first sewing machine.
