Housing materials
The housing materials of the Bsun Tuzi (Bunny) and the Gazzew U4 differ mainly in their top housing material. The Tuzi (Bunny) utilizes a polycarbonate top housing, which produces a sharper, higher-pitched, and crisper sound profile. On the other hand, the U4 features a proprietary Gazzew blend top housing, known for delivering a rich and deep sound profile due to its softness. While the Tuzi's polycarbonate top housing creates a more resonant sound, the U4's unique plastic blend provides a deeper tone, offering users a variety of sound profiles to choose from based on personal preference.
In terms of bottom housing, both the Tuzi (Bunny) and the Gazzew U4 employ a softer plastic material. The Tuzi's nylon bottom housing elicits a deeper and fuller sound profile due to its softness, absorbing more sound and creating a duller and rounder sound. Similarly, the U4's proprietary Gazzew blend bottom housing, also known as "boba plastic," delivers a rich and deep sound profile thanks to its soft composition. Both switches offer a softer bottom housing material that enhances the overall sound experience and provides a more cushioned bottom-out feel compared to harder plastics.
Although the top and bottom housing materials of the Tuzi (Bunny) and Gazzew U4 differ, the overall impact on the sound profile and feel of the switch remains relatively similar. Both switches prioritize creating a rich and deep sound profile, with the Tuzi focusing on sharper tones with its polycarbonate top housing and nylon bottom housing, while the U4 offers a more mellow sound with its Gazzew blend top and bottom housings. Whether your preference lies in a crisper sound or a deeper tone, both switches provide high-quality options for users looking to enhance their typing experience with unique housing materials.
Weight
The Bsun Tuzi (Bunny) linear switch has a lighter actuation force and bottom out force compared to the Gazzew U4 tactile switch. The Tuzi requires 37 grams of force to actuate a keystroke and 42 grams to bottom out, making it a lighter option overall. On the other hand, the U4 needs 45 grams to actuate and 62 grams to bottom out, giving it a medium level of resistance. For those who prefer a lighter typing experience for extended periods, the Tuzi may be the better choice, while the U4 provides a more substantial feel for those who enjoy a heavier push sensation while typing. Both switches offer different levels of force, catering to specific preferences in typing style.
Travel distance
The travel distance of the Bsun Tuzi (Bunny) linear switch and the Gazzew U4 tactile switch are equal, with both having a travel distance of 3.6 mm. Therefore, when it comes to the distance the switch travels from top to bottom, users can expect similar results from both switches. This means that whether you opt for the Tuzi (Bunny) or the U4, you can enjoy a consistent and familiar typing experience in terms of key travel distance.
