Aflion Blush vs. Gazzew U4

Overview

If you're in the market for a new mechanical keyboard switch, you may find yourself torn between the Aflion Blush, a linear switch, and the Gazzew U4, a tactile switch. Both switches offer unique qualities and advantages that can enhance your typing experience. The Blush switch, known as Aflion's best linear offering, stands out for its impressively smooth and snappy feel, thanks to its longer, two-stage spring. Additionally, its long pole provides a satisfying poppy sound signature. On the other hand, the U4 switch from Gazzew offers a sharp and exhilarating tactile bump, delivering a unique typing experience. Furthermore, it offers a plush, felt-like bottom-out sensation, adding to the overall tactile appeal. One distinct advantage of the U4 is its whisper-quiet sound profile, making it ideal for those who prefer a muted typing experience.

Housing materials

The housing materials of the Aflion Blush and the Gazzew U4 differ in terms of their composition and resulting sound profiles. The Blush features a polycarbonate top housing, which creates a sharper and higher-pitched sound. The stiffer nature of polycarbonate enhances the clarity and resonance of the switch, especially when used in conjunction with RGB lighting. In contrast, the U4 utilizes a proprietary Gazzew blend top housing, also known as "boba plastic," to deliver a rich and deep sound profile. This soft plastic blend produces a more mellow and rounded sound upon key release.

Moving on to the bottom housings, the Blush employs a nylon material that generates a deeper and fuller sound profile. Nylon is characterized by its softer composition, which absorbs more sound compared to harder plastics. This results in a duller, yet rounder sound when typing on switches that use nylon bottom housings. Similarly, the U4 incorporates the proprietary Gazzew blend bottom housing, which is designed to contribute to a rich and deep sound profile due to its softness. This "boba plastic" blend mimics the qualities of nylon, resulting in a similar sound experience to the Blush.

Overall, while the Aflion Blush and the Gazzew U4 utilize different housing materials, both switches aim to deliver a satisfying and distinct sound profile. The Blush's polycarbonate top housing and nylon bottom housing create a sharper and deeper sound, respectively. In contrast, the U4's proprietary Gazzew blend top and bottom housing materials contribute to a rich and deep sound. Although the specific nature of their sound profiles may vary, both switches strive to provide an immersive typing experience that enthusiasts find appealing.

Weight

When comparing the actuation force and bottom out force of the Aflion Blush linear switch and the Gazzew U4 tactile switch, there are some similarities and differences to consider. In terms of actuation force, the Blush's weight remains unknown, while the U4 requires 43 grams of force to trigger a keystroke. This means that the U4 has a lighter actuation force, which may be preferred by those who enjoy a lighter typing experience.

Moving on to bottom out force, the Blush requires 58 grams of force to reach the bottom, providing a medium level of resistance. On the other hand, the U4 has a slightly heavier bottom out force of 62 grams, again falling within the medium range. Both switches offer a similar level of resistance when fully pressed.

Considering weight, some individuals prefer lighter switches for extended typing sessions or long gaming sessions, as it allows for less fatigue over time. In this case, the U4's lighter actuation force may be more appealing. However, others may prefer a more substantial typing experience, requiring a stronger push feel. For such individuals, the Blush's bottom out force could provide a more satisfying tactile feedback.

In summary, the Gazzew U4 tactile switch has a lighter actuation force compared to the Aflion Blush linear switch. However, both switches offer a similar medium level of resistance when bottomed out. Ultimately, the choice between the two will depend on individual preferences for typing experience and the desired level of resistance.

Travel distance

When comparing the travel distance of the Aflion Blush linear switch and the Gazzew U4 tactile switch, we find that the Blush has a shorter travel distance of 3.3 mm, while the U4 has a slightly longer travel distance of 3.6 mm. Both switches fall within the range of shorter travel distances, which have become more prevalent in recent times. Gamers, in particular, often prefer shorter travel distances for faster response times. If you prioritize quick responsiveness, the Blush would be a suitable choice. On the other hand, some individuals may find shorter travel distances to be too abrupt, favoring a switch with a longer travel distance like the U4 for a more satisfying depth to their key presses. Ultimately, the decision between the two switches comes down to personal preference and the desired typing experience.
