HMX Gravel vs. Bsun Tomcat

An in-depth look at the HMX Gravel and the Bsun Tomcat switches—which one is the best fit for you?

Overview

When it comes to choosing the right mechanical keyboard switch, both the HMX Gravel and Bsun Tomcat offer unique advantages that cater to different preferences. The HMX Gravel switches are celebrated for their exceptional smoothness and refined typing feel, making them an ideal choice for users who value a light and effortless typing experience. With a medium-light actuation force, the Gravel provides responsive feedback without sacrificing comfort, perfect for both typing and gaming enthusiasts who appreciate a swift keystroke. On the other hand, Bsun Tomcat switches stand out for their Ly stems, which contribute to a notably smooth typing experience, while also delivering a resonant sound profile that many users find satisfying. This makes the Tomcat a great option for those who enjoy auditory feedback alongside tactile performance. While both switches offer a linear experience, their distinct characteristics will appeal to different users. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials

The HMX Gravel and Bsun Tomcat utilize similar materials in their housing constructions, specifically polycarbonate for the top housing and nylon for the bottom housing. This uniformity in material selection leads to a comparably enhanced auditory experience, as both switches possess a polycarbonate top housing that delivers a sharper, higher-pitched sound profile. The stiffness of polycarbonate contributes to the clarity and resonance of the sound produced, making it an optimal choice for those who appreciate crisp auditory feedback. Furthermore, the translucency of the polycarbonate allows for effective RGB lighting integration, enhancing the visual appeal of both switches.

In contrast, the bottom housing of both switches is constructed from nylon, which is known for its softer texture and sound-absorbing qualities. This feature results in a deeper, fuller sound profile that differs from the clearer tones produced by the polycarbonate tops. The nylon's ability to absorb sound reduces noise, culminating in a more muted and rounded auditory experience when typing. As a result, the sound qualities diverge between the top and bottom housings, allowing users to enjoy the unique characteristics each material brings to the overall performance of the switches.

When comparing the overall sound experience of the HMX Gravel and Bsun Tomcat, one can expect similar results due to the parallel use of polycarbonate and nylon in their constructions. While the Gravel may produce a crisper sound upon key release thanks to its polycarbonate top, the Tomcat creates a comparable auditory signature due to its identical material composition. Conversely, both switches will provide a deeper sound upon bottoming out, reflecting the influence of their nylon bottom housings. Thus, the combination of materials creates a balanced auditory performance, with each switch offering distinct yet harmonious sound qualities that stem from their shared material foundation.

Weight

The HMX Gravel linear switch and the Bsun Tomcat linear switch both have the same actuation force of 45 grams, making them comparable in terms of the force required to trigger a keystroke. However, they differ in their bottom out forces; the Gravel has a bottom out force of 50 grams, while the Tomcat's bottom out force is slightly higher at 54 grams. As a result, users of the Gravel switch may experience a slightly lighter overall feel, which could be beneficial for longer typing sessions or gaming marathons. In contrast, the Tomcat, with its heavier bottom out force, may appeal to those who prefer a more substantial typing experience, providing a noticeable resistance that can enhance tactile feedback. Thus, while both switches are commendable for their actuation feel, the Gravel is the lighter option and would suit users favoring extended use without fatigue, whereas the Tomcat is marginally heavier and caters to those who prefer a firmer push.

Travel distance

When comparing the travel distances of the HMX Gravel linear switch and the Bsun Tomcat linear switch, it is evident that the Gravel features a travel distance of 3.5 mm, while the Tomcat offers a slightly longer travel distance of 3.6 mm. The difference of just 0.1 mm indicates that while both options are relatively close, the Tomcat provides a marginally deeper feel, which may appeal to users who prefer a bit more depth in their keystrokes. The Gravel's shorter travel distance might be more suitable for gamers seeking quicker response times, as shorter distances are typically favored for their rapid actuation. In contrast, the Tomcat may satisfy those who enjoy a more pronounced keystroke, so they feel more in control. Ultimately, the choice between the two switches depends on personal preference for either responsiveness or a more traditional keystroke depth.

Typing experience

In terms of sound, the HMX Gravel switch is notable for its smooth operation, although details on its acoustic attributes remain unspecified. On the other hand, the Bsun Tomcat switch produces a resonant sound profile, which suggests a distinct auditory experience when typing. Keep in mind that the sound produced can greatly depend on the specific keyboard build, including factors like the choice of the board and keycap materials, so users may find differences in auditory feedback even between the two switches.

When it comes to feel, the HMX Gravel switch is distinguished by its exceptional smoothness and refined typing sensation, providing a medium-light actuation force that leans toward the lighter side. This feature contributes to a responsive and effortless typing experience. Conversely, the Tomcat switch boasts Ly stems that are engineered for a super smooth typing experience, though additional details about the actuation force or overall tactile feedback are lacking. Despite the differences in design, both switches aim to provide a satisfying feel, appealing to enthusiasts seeking comfort during extended typing sessions.

Considering the overall information available, both the HMX Gravel and Bsun Tomcat linear switches cater to users who appreciate smoothness in their typing experience. While the Gravel focuses on a refined feel and lighter actuation force, the Tomcat highlights its resonant sound and also promises a super smooth operation. In choosing between them, the final preference may come down to personal taste in sound and how each switch integrates with one's specific keyboard setup, as both offer characteristics that are highly regarded among mechanical keyboard enthusiasts.

Conclusion

To conclude, when deciding between the HMX Gravel and Bsun Tomcat linear switches, your personal typing preferences and overall use case should guide your choice. If you prioritize an exceptionally smooth and light typing experience, the HMX Gravel will likely serve you well, especially if you enjoy a keyboard that allows for quick and effortless keystrokes without strain on your fingers. This switch's 50-gram bottom-out force makes it an excellent option for prolonged typing sessions or fast-paced gaming, where a lighter touch can enhance performance. Conversely, if you prefer a slightly heavier feel with a robust tactile sound profile that still maintains smoothness, the Bsun Tomcat might be more suitable for you. With its 54-gram actuation force, it offers a medium-light feel that strikes a balance between responsiveness and weight, catering well to users who appreciate a more resonant sound and a bit more resistance in their keystrokes. Ultimately, your choice should reflect what kind of typing experience feels best to you, whether that's the quick responsiveness of the Gravel or the satisfying heft of the Tomcat.
