TKC Kiwi vs. Bsun Tuzi (Bunny)
An in-depth look at the TKC Kiwi and the Bsun Tuzi (Bunny) switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, two popular options to consider are the TKC Kiwi, a tactile switch, and the Bsun Tuzi (Bunny), a linear switch. The Kiwi switches are designed to provide a satisfying typing experience with a medium to medium-strong bump at the top of each key press, accompanied by a snappy sound profile. They come lightly factory lubed for a smooth and effortless typing feel. On the other hand, the Tuzi switches offer a refined typing experience with a modified LY stem, PC top, and PA bottom for an optimal balance of clack and smoothness. The Tuzi switches are categorized as ['Clacky', 'High-pitched', 'Silky'], while the Kiwi switches are categorized as ['Stepped', 'Low-pitched', 'Neutral', 'Accented', 'Polished']. Each switch has its unique characteristics that cater to different preferences, so it ultimately comes down to personal preference when choosing between them. However, let's dive deeper beyond these generalities to help you make the best decision for your typing needs.

Housing materials
The housing materials of the TKC Kiwi and the Bsun Tuzi (Bunny) exhibit notable differences in their composition and resulting sound profiles. The Kiwi's UHWMPE top housing offers a very bright and resonant sound signature, while the Tuzi's polycarbonate top housing produces a sharper and crisper sound profile. The UHWMPE top housing provides a unique typing experience with its bright clacks, while the polycarbonate top housing offers a distinct high-pitched sound that is enhanced by its stiffness. Additionally, the translucency of polycarbonate makes it ideal for showcasing RGB lighting effects, adding an aesthetic element to the switch.
In terms of bottom housing materials, the Kiwi features UHWMPE which also contributes to its bright sound signature, creating resonant clacks during typing. In contrast, the Tuzi utilizes nylon for its bottom housing, resulting in a deeper and fuller sound profile. The softer nature of nylon allows it to absorb more sound, leading to a duller and rounder sound compared to the brighter sound produced by UHWMPE. This difference in sound profile between the two bottom housing materials can significantly impact the overall typing experience and the acoustic feedback provided by each switch.
While the top and bottom housing materials of the TKC Kiwi and the Bsun Tuzi (Bunny) offer distinct sound profiles, they both play a crucial role in shaping the overall typing experience. The qualities of the housing materials are split between the top and bottom of the switch, with the bottom housing influencing the bottom-out sound and feel, and the top housing affecting the sound when releasing a key. Both switches showcase how different housing materials can contribute to the overall sound and feel of a switch, providing users with unique typing experiences based on their preferences for sound profiles. Despite the differences in materials used, both switches offer distinct advantages in sound quality and aesthetics, catering to a range of user preferences.
Weight
The TKC Kiwi tactile switch and the Bsun Tuzi (Bunny) linear switch have different actuation forces and bottom out forces. The Kiwi has an actuation force of 43 grams and a bottom out force of 67 grams, making it a medium-heavy switch. In contrast, the Tuzi (Bunny) has an actuation force of 37 grams and a bottom out force of 42 grams, which is on the lighter side. The Kiwi requires a stronger push for typing, providing a more substantial typing experience, while the Tuzi (Bunny) is lighter, making it ideal for longer typing sessions or gaming. Both switches offer unique typing experiences based on their respective actuation and bottom out forces, catering to different preferences.
Travel distance
The TKC Kiwi tactile switch has a travel distance of 4 mm, while the Bsun Tuzi (Bunny) linear switch has a travel distance of 3.6 mm. The Kiwi has a slightly longer travel distance, which may offer a bit more depth and feedback compared to the Tuzi. However, both switches fall within the realm of traditional travel distances and should provide a comfortable typing experience for most users. Gamers may prefer the slightly shorter travel distance of the Tuzi for quicker response times, while those who enjoy a more substantial key press may opt for the Kiwi. Ultimately, the choice between the two switches will come down to personal preference in terms of typing feel and response.

Typing experience
When it comes to sound, the TKC Kiwi offers a low-pitched and neutral sound profile, providing a bass-heavy and mellow tone that is suitable for a variety of typing environments. In contrast, the Bsun Tuzi (Bunny) produces a clacky and high-pitched sound, giving off a sharp and crisp noise that may be preferred by those who enjoy a more pronounced auditory feedback during typing sessions. Keep in mind that the sound of a switch can also be influenced by other factors such as the keyboard's construction and the type of keycaps used.
In terms of feel, the TKC Kiwi provides a stepped, accented, and polished typing experience, offering a two-stage tactile feel that is not overly pronounced but still provides a satisfying bump with smooth key travel due to factory lubrication. On the other hand, the Bsun Tuzi (Bunny) is described as silky, emphasizing an extremely smooth keystroke with minimal resistance when pressing and releasing keys. This difference in feel may cater to individuals who prioritize a buttery-smooth typing sensation over a more pronounced tactile bump.
Overall, the TKC Kiwi and Bsun Tuzi (Bunny) switches offer distinct qualities in both sound and feel. If you prefer a low-pitched and neutral sound with a stepped, accented, and polished tactile feel, the Kiwi switch may be the better choice for you. However, if you enjoy a clacky and high-pitched sound paired with a silky smooth keystroke, the Tuzi (Bunny) switch would be more suitable. Ultimately, the decision between these two switches will come down to personal preference and the type of typing experience you desire.
Conclusion
To sum up, if you are looking for a tactile switch with a medium to medium-strong bump at the top of each key press, a smooth and effortless typing experience, and a low-pitched, neutral sound profile, then the TKC Kiwi tactile switch would be a great choice for you. On the other hand, if you prefer a linear switch with a light bottom out force, a refined typing experience with a clacky, high-pitched sound profile, and an exceptionally smooth typing feel, then the Bsun Tuzi (Bunny) linear switch would be more suited to your preferences. Ultimately, the decision between these two switches will come down to your personal typing preferences and the type of typing experience you are looking to achieve.
