Housing materials

The Aflion Thunder Shadow utilizes a polycarbonate top housing, known for creating a sharper and crisper sound profile. In contrast, the Gazzew U4 features a proprietary Gazzew blend top housing, which produces a deep and rich sound profile due to its softness. While both materials aim to enhance sound quality, the polycarbonate top housing of the Thunder Shadow is more likely preferred for those looking for a clear and resonant sound, especially when paired with RGB lighting. On the other hand, the Gazzew U4's top housing provides a softer and warmer sound experience, appealing to those who prioritize depth in their typing experience.

In terms of bottom housing materials, the Thunder Shadow incorporates a nylon bottom housing, offering a deeper and fuller sound profile due to its softness. Similarly, the Gazzew U4 uses a proprietary Gazzew blend bottom housing, also known as "boba plastic," to deliver a rich and deep sound profile. Both materials focus on creating a rounder sound that absorbs more sound than harder plastics. The nylon bottom housing of the Thunder Shadow and the Gazzew blend bottom housing of the U4 aim to enhance the overall sound experience, catering to individuals who appreciate a more muffled and immersive typing sound.

Overall, while the Aflion Thunder Shadow and the Gazzew U4 differ in their housing materials, they both aim to enhance the sound profile of the switches they are used in. The use of polycarbonate in the Thunder Shadow's top housing provides a clear and resonant sound, while the Gazzew blend top housing in the U4 offers a rich and deep sound. Similarly, the nylon bottom housing of the Thunder Shadow and the Gazzew blend bottom housing of the U4 focus on creating a fuller and rounder sound. Both switches prioritize sound quality, providing users with a unique typing experience based on their preferences for sound characteristics.

Weight

The actuation force and bottom out force of the Aflion Thunder Shadow and Gazzew U4 tactile switches differ in several aspects. The Thunder Shadow has a bottom out force of 63.5 grams, which is considered medium-heavy, while its actuation force is unspecified. In comparison, the Gazzew U4 has a lower actuation force of 45 grams and a slightly lighter bottom out force of 62 grams, which is also medium. The difference in actuation force between the two switches means that the Gazzew U4 will require less force to register a keystroke compared to the Thunder Shadow, potentially providing a lighter typing experience. On the other hand, both switches have a similar bottom out force, offering a consistent typing feel in terms of resistance when pressing the keys all the way down. Ultimately, the choice between the two switches will depend on whether a lighter or heavier force is preferred for typing or gaming purposes.

Travel distance

The Aflion Thunder Shadow tactile 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 range of shorter travel distances, which are popular for their faster response times, particularly favored by gamers. The subtle difference in travel distance between the two switches may not be noticeable to most users, and they will likely provide similar results in terms of typing or gaming experience. Ultimately, the decision between the two switches may come down to personal preference regarding the feel of the key press - whether you prefer a slightly shorter travel distance with the Thunder Shadow or a slightly longer one with the U4.
