HMX SU vs. Gazzew U4T
An in-depth look at the HMX SU and the Gazzew U4T switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, the choice between the HMX SU and the Gazzew U4T can greatly affect your typing experience. The HMX SU, a linear switch, is renowned for its smooth operation thanks to its full PA12 housing and T5 stem, providing a subtle yet relatively deep sound profile that appeals to those who prefer a clean and uninterrupted keystroke. This makes it an excellent option for gamers or typists seeking speed and fluidity without the distraction of tactile bumps or clicks. In contrast, the Gazzew U4T presents a tactile experience with its signature bassy "thock" sound profile and sharp tactile feedback, creating an engaging auditory experience that enhances each keystroke. This switch is ideal for users who appreciate both sound and feel in their typing experience and prefer the physical sensation of a tactile response. While both switches have unique offerings that cater to different preferences, let's dive in a bit deeper beyond generalities so you can best decide on the switch that suits your needs.

Housing materials
When comparing the housing materials of the HMX SU and the Gazzew U4T switches, it's essential to note that both utilize nylon for their construction, albeit with the U4T introducing a proprietary blend often referred to as "boba plastic." The HMX SU employs classic nylon for both the top and bottom housing, which is well-known for its ability to create a deeper and fuller sound profile. The softness of nylon allows it to absorb sound more effectively than harder plastics, contributing to a duller and rounder auditory experience. This characteristic is echoed in the Gazzew U4T, where the proprietary blend also aims to deliver a rich sound profile due to its similar softness. Thus, both switches leverage soft housing materials that facilitate an enjoyable and muted sound experience.
However, even though both the HMX SU and Gazzew U4T use softer plastics that contribute to similar sound profiles, the nuances of their materials can lead to differences. The Gazzew U4T employs its unique blend for both the top and bottom housing, which might afford it some distinct acoustic properties when compared to the more uniform nylon of the HMX SU. The implications of these differences will manifest in the auditory feedback and tactile responses during use. For instance, while both switches can deliver a fuller sound when keys are released, the unique properties of "boba plastic" in the U4T may lead to slight variations in the bottoming-out sound, allowing for a distinct experience when pressing down on keys.
Ultimately, while the housing materials of the HMX SU and Gazzew U4T switch offer different formulations—classic nylon versus proprietary boba plastic—they both create similar outcomes in terms of sound quality due to their shared traits of softness and sound absorption. Users seeking a rich auditory experience can expect satisfactory results from either switch. However, the subtleties in material composition suggest that those who place a premium on the nuances of sound or tactile feedback may appreciate the differences offered by the Gazzew U4T's specialized blend compared to the more conventional nylon of the HMX SU.
Weight
When comparing the actuation and bottom out forces of the HMX SU linear switch and the Gazzew U4T tactile switch, it becomes clear that they cater to different preferences in typing feel. The HMX SU has a light actuation force of 45 grams and a bottom out force of 50 grams, making it ideal for users who prefer a softer touch, which can facilitate extended typing sessions without fatigue. In contrast, the Gazzew U4T does not specify an actuation force, but it has a heavier bottom out force of 65 grams, positioning it in the medium-heavy category and appealing to those who appreciate a more substantial push feel when typing. The absence of an actuation force for the U4T leaves that particular aspect unknown; however, the heavier bottom out force suggests a more pronounced feedback when the key is fully pressed down. Overall, the HMX SU is the lighter option between the two, while the Gazzew U4T provides a firmer typing experience, potentially better suited for users who prefer stronger tactile feedback.
Travel distance
The HMX SU linear switch has a travel distance of 3.6 mm, while the Gazzew U4T tactile switch offers a slightly longer travel distance of 4.0 mm. This means that the SU switch provides a shorter pressing experience compared to the U4T, making it potentially more suitable for gamers seeking quick response times. Conversely, the U4T's longer travel distance may appeal to users who prefer a more substantial feel while typing, delivering a heartier depth that some might find more satisfying. Therefore, if you're looking for responsiveness, the HMX SU with its 3.6 mm travel distance would be the better choice, while those who prefer a deeper keystroke may lean towards the Gazzew U4T's 4.0 mm distance.

Typing experience
The sound characteristics of the HMX SU linear switch are defined by a subtle yet relatively deep sound profile, providing a pleasing auditory experience with each keystroke. This depth can be appreciated, especially when combined with thoughtful keycap choices and the type of keyboard used, as these factors can influence the overall acoustic performance. In contrast, the Gazzew U4T tactile switch offers a more robust auditory experience, known for its bassy and thocky sound profile. The U4T produces a deeper, richer sound that resembles a satisfying thud upon key presses, making it particularly appealing for users who enjoy auditory feedback and a more immersive typing experience. While both switches provide enjoyable sound profiles, the U4T stands out with its distinct thockiness.
When it comes to feel, the HMX SU linear switch provides a smooth and uninterrupted keystroke, typical of linear switches that focus on the fluidity of motion without the presence of tactile feedback. This allows for a consistent keystroke experience, which is ideal for users who prefer a seamless typing sensation. Conversely, the Gazzew U4T tactile switch is characterized by a sharp tactile bump that delivers strong feedback with each press, giving users a heightened sense of engagement with their typing. This crisp tactile sensation can enhance typing accuracy and provide a more dynamic interaction compared to the smoother feel of linear switches like the SU.
In conclusion, choosing between the HMX SU linear switch and the Gazzew U4T tactile switch ultimately comes down to personal preference. The SU offers a quiet, smooth typing experience with a subtle sound, appealing to those who prioritize stealth and fluidity. Meanwhile, the U4T boasts a pronounced tactile feel and distinctive sound profile, making it a favorite for users seeking auditory and tactile satisfaction. Both switches cater to different typing experiences, and understanding these qualities will aid newcomers in selecting the type of switch that fits their unique style and requirements.
Conclusion
To conclude, your choice between the HMX SU linear switch and the Gazzew U4T tactile switch largely depends on your typing preferences and the kind of experience you seek. If you prefer a lighter touch and enjoy a smoother keystroke without tactile feedback, the SU linear switch is an excellent choice. Its 50-gram bottom-out force allows for effortless key presses, making it ideal for fast typists who value speed and consistency over tactile sensation. The relatively deep and subtle sound it produces is perfect if you want a quieter typing experience while still maintaining a pleasant auditory profile. On the other hand, if you appreciate a more pronounced typing experience with clear tactile feedback, the U4T tactile switch is the way to go. With a medium-heavy 65-gram bottom-out force, it gives you a robust resistance that can help reduce typing fatigue during long sessions. The unique combination of its bassy thock sound and sharp tactile bump provides an engaging auditory and tactile satisfaction, making each keystroke feel rewarding. Therefore, consider what you prioritize in your mechanical keyboard experience: if you're drawn to a softer, linear feel, opt for the HMX SU; but if you seek a dynamic tactile sensation, the Gazzew U4T will likely meet your needs better.
