An in-depth look at the KTT F2 and the Gazzew U4 switches—which one is the best fit for you?

Overview

When looking for the perfect mechanical keyboard switch, the choice often comes down to preferences in sound, feel, and overall typing experience. The KTT F2, a linear switch, offers a unique hollow sound signature that sets it apart in the auditory realm. With a medium-light weightiness and lightly textured feel, each keystroke on the F2 provides a comfortable yet tactile typing experience. On the other hand, the Gazzew U4, a tactile switch, boasts a sharp and exhilarating tactile bump accompanied by a plush, felt-like bottom-out sensation. Its whisper-quiet sound profile adds a touch of subtlety to its overall performance. Each switch is categorized differently; the F2 as 'Feathery', 'Mild', 'Neutral', 'Subdued', 'Subtle', and the U4 as 'Muted', 'Low-pitched', 'Sharp'. Ultimately, the choice between these two switches comes down to personal preferences in sound, feel, and typing style. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials

In comparing the housing materials of the KTT F2 and the Gazzew U4, both switches feature polycarbonate in their top housings. Polycarbonate is known for creating a sharper, higher-pitched, and crisper sound profile due to its stiffness. The use of polycarbonate in the top housing of a switch is especially beneficial for showcasing RGB lighting, thanks to its translucency. On the other hand, the Gazzew U4 utilizes a proprietary plastic blend known as "boba plastic" in its top housing, which delivers a rich and deep sound profile due to its softness. While both materials offer unique sound profiles, the polycarbonate in the F2 leans towards a clearer and more resonant sound, while the "boba plastic" in the U4 provides a deeper and richer tone.

Moving on to the bottom housings, both the KTT F2 and the Gazzew U4 feature polycarbonate in their respective bottom housings. Just like in the top housing, polycarbonate in the bottom housing of a switch contributes to a sharper, higher-pitched, and crisper sound profile. This stiffness of polycarbonate enhances the clarity and resonance of the sound produced. In contrast, the Gazzew U4 utilizes its proprietary "boba plastic" blend in the bottom housing, which delivers a rich and deep sound profile thanks to its softness. Despite the difference in materials used, both switches benefit from the unique sound characteristics brought by their respective bottom housings.

Overall, while the housing materials used in the KTT F2 and the Gazzew U4 offer distinct sound profiles, they both excel in creating high-quality and unique typing experiences. The polycarbonate top and bottom housings of the F2 contribute to a sharper, clearer sound profile with a hint of resonance, while the proprietary "boba plastic" blend utilized in the U4's top and bottom housings deliver a rich, deep sound profile. Both switches showcase the importance of housing materials in creating an enhanced typing experience, with each material bringing its own unique qualities to the table. Whether you prefer a crisper sound or a deeper tone, both switches offer a premium typing experience through their carefully chosen housing materials.

Weight

When comparing the actuation force and bottom out force of the KTT F2 linear switch and the Gazzew U4 tactile switch, the F2 has a lighter actuation force of 43 grams compared to the U4's 45 grams. Additionally, the F2 has a lower bottom out force of 53 grams, while the U4 requires a heavier 62 grams to bottom out. The F2 provides a lighter typing experience overall, making it ideal for extended typing sessions or gaming marathons where fatigue is a concern. On the other hand, the U4 offers a more substantial typing feel with its heavier bottom out force, appealing to users who prefer a stronger push sensation for their keystrokes. Overall, the F2 is lighter in actuation and bottom out force compared to the U4, making it a better choice for those seeking a lighter typing experience.

Travel distance

The KTT F2 linear switch has a travel distance of 3.5 mm, while the Gazzew U4 tactile switch has a slightly longer travel distance of 3.6 mm. Both switches fall within the shorter travel distance range, making them popular choices for those looking for a faster response time, such as gamers. The difference of 0.1 mm between the two may not be significant in terms of feeling the difference when pressing down on a key. Ultimately, the choice between the two switches may come down to personal preference, with those favoring a slightly longer travel distance potentially opting for the Gazzew U4 tactile switch for a slightly more pronounced feeling when typing.
