Housing materials

The Aflion Blush and the SP-Star Duck have similar housing materials in their top housings, both utilizing polycarbonate. This material choice enhances the sound profile of the switches, creating a sharper, higher-pitched, and crisper sound when typing. Additionally, the translucency of polycarbonate allows for RGB lighting to shine through, adding aesthetic appeal. However, while the Blush's top housing focuses on the sound profile, the Duck's top housing emphasizes its visual impact. Overall, the polycarbonate top housing in both switches provides a similar experience in terms of sound and lighting capabilities.

In contrast, the Blush and the Duck differ in their choice of materials for the bottom housing. The Blush features a nylon bottom housing, which produces a deeper and fuller sound profile when typing. Nylon, being a softer plastic, absorbs more sound, resulting in a duller and rounder sound. On the other hand, the Duck opts for a polycarbonate bottom housing, aligning with its top housing material. This choice maintains the sharper and crisper sound profile associated with polycarbonate, providing a more consistent and resonant typing experience. While the impact of the bottom housing is felt during bottom-out sound and feel, the top housing's influence is more prominent when releasing a key.

When considering the overall qualities brought by the housing materials, the Blush and the Duck offer slightly different experiences. The Blush with its polycarbonate top housing delivers a sharp and clear sound profile, complemented by the deeper and fuller sound of its nylon bottom housing. This combination creates a dynamic and well-rounded typing experience. In contrast, the Duck's polycarbonate top and bottom housings result in a consistently sharp and resonant sound profile throughout the keystroke. Both switches prioritize sound quality, but the Blush places more emphasis on a balanced sound, while the Duck prioritizes a consistently crisp sound. Overall, both switches provide unique experiences, highlighting the importance of housing materials in dictating sound profiles.

Weight

When comparing the actuation force and bottom out force of the Aflion Blush linear switch and the SP-Star Duck tactile switch, it is important to note that both switches have an actuation force that is unspecified. However, they both have a bottom out force of 58 grams, which can be considered medium in terms of force required for typing.

Weight is an important factor to consider when choosing a switch, as it can significantly affect the typing experience. For those who prefer a lighter switch, the Aflion Blush may be the better option. A lighter switch allows for longer typing sessions without causing fatigue, making it suitable for use in professional environments or during extended gaming sessions.

On the other hand, individuals who prefer a more robust and substantial typing experience may lean towards the SP-Star Duck. With a heavier force required to bottom out, these switches provide a stronger push feel, which can be satisfying for users who enjoy a more pronounced tactile feedback while typing.

In summary, while both the Aflion Blush and SP-Star Duck have an unfixed actuation force, they share the same bottom out force of 58 grams, which is considered medium. For those seeking a lighter typing experience, the Aflion Blush may be the ideal choice, whereas those who prefer a heavier and more substantial feel may find the SP-Star Duck more to their liking.

Travel distance

The Aflion Blush linear switch has a travel distance of 3.3 mm, while the SP-Star Duck tactile switch has a travel distance of 4 mm. This means that the Duck has a slightly longer travel distance compared to the Blush. Generally, a travel distance of 4.0 mm is considered to be the most traditional, while 3.0 mm is the most shallow. However, in recent times, shorter travel distances have become prevalent, particularly among gamers who prioritize faster response times. For those seeking a more responsive typing experience, the shorter travel distance of the Blush would be a suitable choice. On the other hand, some individuals find short travel distances to feel too abrupt and prefer switches with more depth. In this case, the Duck's longer travel distance may be the preferred option. Ultimately, the choice depends on personal preferences and the desired typing experience.
