Bsun Tomcat (Heavy) vs. Gazzew U4T

An in-depth look at the Bsun Tomcat (Heavy) and the Gazzew U4T switches—which one is the best fit for you?

Overview

When choosing between mechanical keyboard switches, the Bsun Tomcat (Heavy) and the Gazzew U4T offer distinct yet compelling experiences that cater to different preferences. The Tomcat (Heavy) is renowned for its linear design, featuring Ly stems that provide a super smooth typing experience, complemented by a resonant sound profile that appeals to those who enjoy quiet yet satisfying keystrokes. In contrast, the Gazzew U4T embodies a unique blend of tactility and acoustics; its assertive tactile feedback and bassy 'thock' sound deliver an engaging and immersive typing experience, perfect for users who relish the auditory satisfaction that each keystroke brings. Whether you prioritize the smoothness of a linear switch or the pronounced feedback of a tactile one, each switch shines in its own right. However, let's dive in a bit deeper beyond generalities, so you can best decide on the right switch for you.

Housing materials

When comparing the housing materials of the Bsun Tomcat (Heavy) and the Gazzew U4T, notable differences emerge in the top housings of each switch. The Tomcat (Heavy) utilizes a polycarbonate top housing, which is known for its rigidity and translucency. This material contributes to a sharper, higher-pitched sound profile, enhancing clarity and resonance, particularly beneficial when RGB lighting is incorporated. In contrast, the U4T features a proprietary blend referred to as "boba plastic," which, while providing a visually appealing aesthetic, tends to yield a richer and deeper sound profile due to its softer nature. While both materials serve to enhance sound quality, the Tomcat (Heavy) leans towards producing clearer high frequencies, whereas the U4T embraces a warmer and fuller audio experience.

Turning to the bottom housings, both switches share an interesting similarity with their use of softer materials. The Tomcat (Heavy) employs a nylon bottom housing, celebrated for its ability to generate a deep and well-rounded sound profile through sound absorption. Meanwhile, the Gazzew U4T continues the trend with its proprietary "boba plastic" bottom housing, which also fosters a rich sound signature. The use of these softer materials in both switches signifies an intentional design choice to create a rounder auditory experience, even though they diverge in the top housing influences. Consequently, while the Gazzew U4T's sound might lean towards fullness due to the blend of both housings, the Tomcat (Heavy) will maintain a distinct character from the polycarbonate top.

In essence, if one were to use these switches in tandem, it would be possible to achieve similar auditory results—albeit with different tonal nuances—thanks to the commonality of softer materials in their bottom housings. The Tomcat (Heavy) excels in clarity and brightness from its polycarbonate top, while the U4T's top housing softens the sound profile, allowing both switches to cater to varied personal preferences. Ultimately, the unique material combination in each switch contributes to their individual qualities, allowing users to tailor their typing experience based on the desired sound profile. Whether opting for the sharper tones of the Tomcat (Heavy) or the warmer nuances of the U4T, one can appreciate the specificity of housing materials in crafting a satisfying auditory experience.

Weight

When comparing the actuation and bottom out forces of the Bsun Tomcat (Heavy) linear switch and the Gazzew U4T tactile switch, notable differences emerge in their specifications. The Tomcat (Heavy) has a measured actuation force of 55 grams and a bottom out force of 64 grams, classifying it as medium-heavy. In contrast, while the U4T's bottom out force is slightly higher at 65 grams, its actuation force is unspecified. This omits a direct comparison for triggering a keystroke; however, given that the bottom out force is similar, it suggests that users may experience comparable levels of resistance when reaching the end of the keypress. In terms of weight, the Tomcat (Heavy) is the lighter option for actuation, potentially appealing to those who prefer a lighter touch for extended typing or gaming sessions. Meanwhile, the U4T may offer a more substantial feel due to its unknown actuation force and slightly heavier bottom out force, which might cater to users seeking a stronger push experience.

Travel distance

When comparing the travel distances of the Bsun Tomcat (Heavy) linear switch and the Gazzew U4T tactile switch, the Tomcat (Heavy) measures at 3.6 mm, while the U4T features a slightly longer travel distance of 4 mm. This difference positions the Tomcat (Heavy) as the shorter option, making it potentially more appealing for gamers seeking quicker response times and a more immediate tactile feedback when pressing keys. On the other hand, the U4T, with its longer travel distance, may cater to users who appreciate a more substantial feel and depth when typing. Ultimately, those who prioritize responsiveness may prefer the Tomcat (Heavy), whereas individuals who enjoy a more traditional keystroke experience might gravitate towards the Gazzew U4T.

Typing experience

In terms of sound, the Bsun Tomcat (Heavy) linear switch produces a resonant sound profile that emphasizes its smooth operation, making it quieter than tactile or clicky switches. The Gazzew U4T, in contrast, is celebrated for its bassy and thocky sound, delivering a deeper and richer auditory experience during key presses. The U4T’s sound can be characterized by pronounced deep "thuds" or soft "knocks," which offer a satisfying auditory cue with every keystroke. While the Tomcat may be more subdued, those who favor a noise profile might find the U4T to be distinctly more engaging and resonant.

Regarding feel, the Bsun Tomcat (Heavy) linear switch is known for providing an exceptionally smooth typing experience attributed to its Ly stems. This results in a fluid action without any tactile bumps, making it ideal for users who prefer a minimalist feel. On the other hand, the Gazzew U4T presents a sharp tactile feedback with a strong, crisp tactile bump that is easily perceptible at every keypress. This high-intensity feedback creates a dynamic typing experience that can be invigorating to those who appreciate tactile switches. The choice between these two feels ultimately depends on whether one desires a smooth, uninterrupted stroke or the pronounced feedback of a tactile switch.

In conclusion, the Bsun Tomcat (Heavy) linear switch offers a smooth typing experience with a more muted sound profile, making it suitable for those who prefer quieter and fluid keystrokes. In contrast, the Gazzew U4T tactile switch captivates with its bassy, thocky sound and sharp tactile feedback, providing users with a more pronounced and satisfying typing experience. Each switch caters to different preferences, so those looking for a specific auditory and tactile satisfaction should consider their desired typing style and sound profile when making their choice.

Conclusion

To conclude, choosing between the Bsun Tomcat (Heavy) linear switch and the Gazzew U4T tactile switch ultimately depends on your typing preferences and intended use. If you prioritize a buttery-smooth typing experience with a more neutral sound profile, the Tomcat (Heavy) is an excellent choice, offering medium-heavy actuation force and a resonant sound that makes it ideal for prolonged typing sessions where comfort is key. This switch shines for tasks that require constant, fluid keystrokes without the interruptions of tactile feedback, such as coding or writing. Conversely, if you enjoy a tactile and auditory delight with each keypress, the Gazzew U4T is your go-to option. Its sharp tactile feedback combined with a rich, thocky sound profile can enhance both typing enjoyment and productivity for tasks like gaming or casual writing where you appreciate a distinct feedback on each keystroke. In essence, your decision should hinge on whether you value a smooth and linear feel over a pronounced tactile bump and satisfying sound with your keyboard experience.
