Bsun Tuzi (Bunny) vs. Gazzew U4Tx
An in-depth look at the Bsun Tuzi (Bunny) and the Gazzew U4Tx switches—which one is the best fit for you?
Overview
When it comes to choosing the right mechanical keyboard switch for your typing experience, the Bsun Tuzi (Bunny) and the Gazzew U4Tx offer distinct options tailored to different preferences. The Tuzi (Bunny), known for its clacky and high-pitched signature, features a modified LY stem that combines a PC top and PA bottom, creating an optimal balance of sound and smoothness for users who enjoy a more expressive typing experience. On the other hand, the Gazzew U4Tx presents a sophisticated tactile alternative, merging the best of both worlds with its deep "thock" sound when bottoming out and a whisper-quiet topping out. This switch not only delivers a sharp tactile bump but also provides a cleaner sound profile that pleases the ears while typing. Each switch caters to varied styles: the Tuzi is perfect for those who relish a lively and engaging sound, whereas the U4Tx appeals to users who prefer a more muted but satisfying tactile feedback. However, let's dive in a bit deeper beyond generalities so you can best decide on the switch that's right for you.

Housing materials
When comparing the housing materials of the Bsun Tuzi (Bunny) and the Gazzew U4Tx, a clear distinction can be identified in the choice of materials for their top housings. The Tuzi (Bunny) utilizes polycarbonate for its top housing, which is known for its stiffness and translucency. This enables a sharper, higher-pitched sound profile and a vibrant aesthetic when RGB lighting is used. In contrast, the U4Tx employs a proprietary blend often referred to as "boba plastic," which is softer and contributes to a richer, deeper sound profile. Thus, while the polycarbonate design of the Bunny enhances brightness and clarity, the U4Tx’s blend promotes warmth and depth, leading to unique auditory experiences when using each switch.
The bottom housings of both switches present a different but interesting comparison. The Tuzi (Bunny) features a nylon bottom housing that is celebrated for its ability to create a fuller, rounder sound. Due to nylon's sound-absorbing qualities, the sound produced is generally more subdued and less harsh. Conversely, the Gazzew U4Tx also uses the proprietary "boba plastic" for its bottom housing, which similarly excels in producing a rich sound profile due to its softness. While both materials can create desired sound characteristics, the nylon of the Bunny emphasizes a deeper, more classic typing feel, while the Gazzew material also aims for rich depth but may vary in texture or feedback based on its proprietary nature.
Ultimately, the differences in sound profiles between the Bsun Tuzi (Bunny) and the Gazzew U4Tx can be attributed to their respective top and bottom housing materials. The Bunny’s polycarbonate top provides a bright and crisp sound, while its nylon bottom softens this with a more rounded tone. On the other hand, the U4Tx’s top housing delivers a deeper sound with its proprietary blend, matched by a similarly rich bottom housing. Therefore, while the switches generate distinct auditory signatures, they may achieve comparably satisfying results through the interplay of their unique materials and designs, catering to varying preferences among typists and gamers alike.
Weight
When comparing the Bsun Tuzi (Bunny) linear switch and the Gazzew U4Tx tactile switch, there are notable differences in their actuation and bottom out forces. The Tuzi (Bunny) presents an actuation force of 37 grams, alongside a bottom out force of 42 grams, making it a lighter option for users who prefer a less strenuous typing experience, ideal for long work sessions or extended gaming. In contrast, the U4Tx has no specified actuation force but features a bottom out force of 62.5 grams, categorizing it as a heavier option. This suggests that, while the Bunny switch requires less force to actuate, it achieves its bottom out more easily than the U4Tx, which demands significantly more pressure when bottoming out. Therefore, individuals seeking a lighter typing feel would gravitate toward the Tuzi (Bunny), while those preferring a more substantial push would likely opt for the U4Tx, given its heavier characteristics.
Travel distance
The Bsun Tuzi (Bunny) linear switch and the Gazzew U4Tx tactile switch both feature an identical travel distance of 3.6 mm, meaning that the distance traveled when pressing down on each key is the same. As a result, users can expect a similar tactile feel in terms of travel distance, contributing to a comparable typing experience between the two switches. Since both switches share the same travel distance, enthusiasts can be assured of similar performance when it comes to key press depth.

Typing experience
When it comes to sound, the Bsun Tuzi (Bunny) linear switches produce a clacky and high-pitched auditory experience. This translates into a sharp, bright, and snappy sound that is both crisp and percussive. Those who appreciate a lively auditory feedback in their typing will find these switches appealing. On the other hand, the Gazzew U4Tx tactile switches offer a more complex sound profile, characterized by a deep, resonant "thock" upon bottoming out and a whisper-quiet sound when topping out. This combination results in a muted yet deep auditory experience that leans towards a bassy tone. While the Tuzi offers a lively and sharp sound, the U4Tx provides a richer depth, making them distinctly different in auditory feedback for users based on personal preference.
In terms of feel, the Tuzi (Bunny) stands out for its silky smoothness, providing an exceptionally refined typing experience with minimal resistance during key presses. This creates a buttery-smooth interaction with the keyboard, suitable for those who prioritize an effortless typing experience. In contrast, the U4Tx tactile switches are designed to deliver a sharp and prominent tactile bump, offering high feedback intensity with each keystroke. This tactile sensation is distinctly felt and provides a different kind of engagement when typing, appealing to users who seek strong tactile confirmation of their key presses. While the Tuzi offers a smooth and fluid experience, the U4Tx emphasizes tactile feedback for a more pronounced interaction.
In conclusion, the Bsun Tuzi (Bunny) linear switches and the Gazzew U4Tx tactile switches present unique auditory and tactile qualities, making them suitable for different typing preferences. The Tuzi is notable for its clacky, high-pitched sound and silky smooth feel, while the U4Tx captivates with its deep, resonant sound and sharp tactile feedback. Depending on whether you prioritize auditory liveliness or tactile precision, each option presents an engaging typing experience tailored to individual tastes. Ultimately, your choice will come down to whether you prefer the lively characteristics of the Tuzi or the refined yet significant tactile satisfaction of the U4Tx.
Conclusion
To wrap up, the choice between the Bsun Tuzi (Bunny) linear switch and the Gazzew U4Tx tactile switch ultimately depends on your personal preferences and typing habits. If you prefer a lighter switch that delivers a quick, smooth, and clacky feel, the Tuzi (Bunny) is an excellent choice. With its low bottoming force of 42 grams, it allows for a refined typing experience that feels effortless, making it an ideal option for fast typists or gamers seeking a smooth keypress. On the other hand, if you enjoy a more tactile and audible feedback with a satisfying "thock" sound when bottoming out, the U4Tx is the way to go. The medium force of 62.5 grams combined with its distinct sharp tactile bump provides an engaging typing experience that offers both depth and richness in sound without being overbearing. Choose the Tuzi (Bunny) when you want a lightweight, silky experience, and opt for the U4Tx when you seek a sturdy, bassy switch that enhances your tactile feedback and auditory pleasure. Ultimately, consider what aspects matter most to you—smoothness vs. tactility, weight, and sound profile—as you make your decision.
