Bsun Tuzi (Bunny) vs. Gazzew U4Tx RGB
An in-depth look at the Bsun Tuzi (Bunny) and the Gazzew U4Tx RGB switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboards, the choice of switches can significantly impact your typing experience, and two noteworthy options are the Bsun Tuzi (Bunny) and the Gazzew U4Tx RGB. The Tuzi (Bunny), characterized as a linear switch, is celebrated for its refined typing experience, featuring a modified LY stem that, when paired with a PC top and PA bottom, creates a unique blend of clack and smoothness. This switch offers a high-pitched, silky feel that’s ideal for users who enjoy a more pronounced sound while typing and desire a seamless keypress action. In contrast, the Gazzew U4Tx RGB is a tactile switch that provides the deep "thock" associated with bottoming out, while ensuring a quiet top-out, producing a luxurious sound profile paired with a sharp tactile bump that many typists appreciate for its feedback and responsiveness. While both switches cater to different preferences—those seeking the lively audio of the Bunny versus the refined feedback and sound of the U4Tx RGB—your final decision ultimately hinges on your personal typing style and aesthetic preference. However, let’s dive in a bit deeper beyond generalities so you can best decide on the switch that suits you.

Housing materials
The housing materials of the Bsun Tuzi (Bunny) and the Gazzew U4Tx RGB switches present a fascinating study in contrasts, particularly in their top housing compositions. The Bunny utilizes a polycarbonate top housing, celebrated for its ability to produce a sharper, higher-pitched sound profile. This stiffer plastic enables a crisper sound that resonates more clearly when a key is released. On the other hand, the U4Tx RGB features a proprietary blend sometimes referred to as "boba plastic," which offers a softer quality that results in a richer and deeper sound. While both materials are engineered to enhance the auditory experience when typing, they contribute contrasting characteristics based on their inherent material properties.
With respect to the bottom housing, both switches embrace a softness that further shapes their overall sound. The Bunny opts for a nylon bottom housing, a traditional choice in the keyboard industry, known for its ability to produce a fuller and deeper auditory output. This is due to the way nylon absorbs sound, thus delivering a rounder tone upon bottoming out. Conversely, the U4Tx RGB employs the same proprietary Gazzew blend for its bottom housing as well, enhancing the depth of sound yet again through its unique softness. Consequently, while the Bunny and the U4Tx RGB utilize different materials for the top housing, they share a commonality in their approach to the bottom housing, which is instrumental in defining the tactile experience when keys are fully pressed.
Ultimately, the dual contributions of top and bottom housing materials come together to create distinctive sound profiles and typing experiences for both switches. For those seeking similar auditory qualities in both switch types, attention should be directed toward the design interplay of the two housings. The Bunny’s polycarbonate top provides a clear release sound, while its nylon bottom softens the bottom-out feel, contributing to a dynamic typing experience. The U4Tx RGB, with its boba plastic blend on both ends, aims for a consistent rich sound throughout. When combined, the differing top materials can manifest in similar sound output if one mixes the auditory characteristics strategically, highlighting the importance of both housing components in creating an ideal typing environment.
Weight
When comparing the Bsun Tuzi (Bunny) linear switch and the Gazzew U4Tx RGB tactile switch, there is a distinct difference in their actuation and bottom out forces. The Tuzi Bunny is notably lighter, featuring an actuation force of 37 grams and a bottom out force of 42 grams, making it an ideal choice for long typing sessions or gaming marathons where fatigue might be a concern. In contrast, the U4Tx RGB switch lacks a specified actuation force but has a heavier bottom out force of 65 grams, indicating a more substantial feel when fully pressed down. This difference in bottom out forces suggests that the U4Tx RGB switch provides a more pronounced tactile feedback for those who prefer a firmer typing experience. Therefore, for users who prioritize a lightweight switch for extended use, the Tuzi Bunny is preferable, while the U4Tx RGB caters to those who seek a stronger push feel.
Travel distance
Both the Bsun Tuzi (Bunny) linear switch and the Gazzew U4Tx RGB tactile switch have an identical travel distance of 3.6 mm. This means that when pressing down on either switch, users will feel the same distance of travel, providing a uniform typing experience in terms of key actuation depth. Consequently, those seeking consistency in key feel will find that both switches offer the same physical response, ensuring similar results during use.

Typing experience
When it comes to sound, the Bsun Tuzi (Bunny) linear switches provide a distinctly clacky and high-pitched auditory profile. Users can expect a sharp and snappy sound upon activation, characterized by a crispness that can make typing feel lively and engaging. In contrast, the Gazzew U4Tx RGB tactile switches incorporate a different sound signature, blending the deep "thock" produced during bottoming out with the quiet “stealth” of the topping out. This combination creates a unique sound profile that offers a rich auditory experience without the brightness typical of clackier switches, appealing to those who prefer something more subdued yet satisfying. It’s important to note that the final sound output can vary significantly depending on the keyboard’s construction and the keycaps used.
Regarding feel, the Tuzi (Bunny) switches are recognized for their silky smoothness, providing an exceptionally fluid typing experience with minimal resistance during key presses and releases. This quality tends to enhance the overall typing experience, making it enjoyable for both typing and gaming. While the Gazzew U4Tx RGB switches deliver a tactile bump that adds a luxurious sensation during use, detailed comparison metrics on their smoothness are not provided. However, one can expect that they will offer a different sensation with the tactile feedback, which can enhance the typing experience in a unique way.
In summary, while the Bsun Tuzi (Bunny) linear switches are characterized by their clacky and high-pitched sound along with a silky feel, the Gazzew U4Tx RGB tactile switches offer a deeper "thock" sound combined with a distinctive tactile feedback. Both switches cater to different preferences in auditory and tactile experiences, ensuring that whether you gravitate towards a lively auditory environment or a softer thumping sound, you can find satisfaction in either type. Ultimately, selecting between them hinges on personal preference for sound characteristics and desired tactile feedback, both promising to deliver enjoyable typing experiences.
Conclusion
To sum up, your choice between the Bsun Tuzi (Bunny) linear switch and the Gazzew U4Tx RGB tactile switch will largely depend on your personal preferences in typing feel and sound profile. If you enjoy a lighter key press and appreciate a clacky, high-pitched sound that provides an engaging auditory feedback, the Tuzi (Bunny) will be an excellent option. Its silky smoothness and low actuation force make it ideal for rapid typing and gaming, allowing you to enjoy a more playful and dynamic experience. On the other hand, if you gravitate towards a more robust typing experience with a medium-heavy actuation force, the U4Tx RGB will likely meet your needs better. Its deep "thock" sound combined with a sharp tactile bump can enhance your typing feel by providing feedback on each keystroke, making it great for both typing and gaming contexts where precision is key. Ultimately, choosing between these switches hinges on whether you prioritize a light and pleasant typing experience or a more pronounced tactile feedback with a richer sound.
