Bsun Guyu vs. Aflion Iceberg
An in-depth look at the Bsun Guyu and the Aflion Iceberg switches—which one is the best fit for you?
Overview
The Bsun Guyu linear switch and the Aflion Iceberg linear switch both offer unique features and qualities that cater to different preferences among mechanical keyboard enthusiasts. The Guyu switch stands out for its distinct auditory experience, featuring all-POM housings that enhance acoustics and a long pole stem for a crisper bottom-out sound. With a medium weight and super-smooth keystrokes, typing on the Guyu switch is effortless and resonant. On the other hand, the Iceberg switch from Aflion boasts a satisfying smoothness and a fulfilling feel, thanks to its two-stage spring design. While the Guyu switch is described as 'creamy,' 'polished,' and 'silky,' the Iceberg switch is known for being 'high-pitched,' 'feathery,' and 'subtle.' Both switches offer unique qualities that cater to different typing preferences. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The Bsun Guyu and Aflion Iceberg switches both have unique housing materials that contribute to their sound profiles. The Guyu's POM top housing creates a deeper and more muted sound, while the Iceberg's polycarbonate top housing produces a sharper, higher-pitched sound. In terms of aesthetics, the polycarbonate top housing of the Iceberg allows for RGB lighting to shine through, adding a visually appealing element to the switch. On the other hand, the Guyu's POM bottom housing also contributes to its sound profile, creating a unique sound experience that is deeper and more muted compared to the Iceberg's nylon bottom housing, which produces a fuller and rounder sound.
Despite their differences, both switches utilize their housing materials to create distinct sound profiles. The split between the top and bottom housing materials in a switch allows for a combination of qualities in both the bottom-out sound and the sound when a key is released. The softer nylon bottom housing of the Iceberg absorbs more sound, resulting in a duller and rounder sound profile, while the stiffer polycarbonate top housing creates a clear and resonant sound. Similarly, the POM materials in the Guyu contribute to a pleasing and unique sound experience with a deeper tone, enhancing the overall typing feel of the switch.
Overall, the choice between the Bsun Guyu and Aflion Iceberg switches may come down to personal preference in sound profile and typing experience. While the Iceberg offers a crisper and higher-pitched sound with its polycarbonate top housing and nylon bottom housing, the Guyu provides a deeper and more muted sound profile with its POM materials. Both switches offer unique qualities that can enhance the typing experience for different users, whether they prefer a sharper sound profile or a deeper, more resonant tone. Ultimately, the housing materials of these switches play a crucial role in shaping the overall sound and feel of each keystroke.
Weight
When comparing the actuation force and bottom out force of the Bsun Guyu linear switch and the Aflion Iceberg linear switch, it is evident that both switches are relatively light. The Guyu has an actuation force of 45 grams and a bottom out force of 50 grams, while the Iceberg has an actuation force of 37 grams and a bottom out force of 45 grams. In this case, the Iceberg switch is lighter in both actuation and bottom out force compared to the Guyu switch. For those who prefer a lighter typing experience, the Iceberg switch may be the better option due to its lower actuation and bottom out forces. However, if someone enjoys a slightly more substantial typing feel, the Guyu switch with slightly higher actuation and bottom out forces could be more suitable. Ultimately, the decision between the two switches will depend on personal preference and typing style.
Travel distance
The travel distance of the Bsun Guyu linear switch is 3.6 mm, while the Aflion Iceberg linear switch has a travel distance of 4 mm. This means that the Iceberg has a slightly longer travel distance compared to the Guyu. The Guyu's 3.6 mm travel distance falls on the shorter end of the spectrum, making it a popular choice among gamers looking for faster response times. On the other hand, the Iceberg's 4 mm travel distance offers a bit more depth, which some users may prefer for a more substantial feel when typing. Ultimately, the choice between the two switches will depend on personal preference for travel distance and feel.

On the other hand, the Aflion Iceberg linear switch also provides a clacky sound profile, but in addition, it offers a high-pitched tone that adds a sharp and crisp element to the typing experience. Both switches cater to those who enjoy a distinct sound signature but with slight variations in tonality.
When it comes to feel, the Bsun Guyu linear switch is best described as offering a creamy, frictionless, and polished typing experience that feels like effortlessly gliding across the keys with a silky sensation. This switch is also noted for its snappy responsiveness, adding a dynamic touch to each keystroke. In contrast, the Aflion Iceberg linear switch provides a snappy typing experience that feels lively and responsive, along with a feathery lightness that reduces finger fatigue during extended typing sessions. The Iceberg switch also offers a subtle resistance, making it suitable for quieter environments.
Overall, both the Bsun Guyu linear switch and the Aflion Iceberg linear switch offer unique qualities in terms of sound and feel. While the Guyu switch provides a medium weight and super-smooth keystrokes for a balanced and resonant sound, the Iceberg switch presents a two-stage spring mechanism for a fulfilling typing feel. Depending on personal preferences for sound profiles and typing experiences, either switch can cater to the needs of different users, delivering satisfying results in typing performance and enjoyment.
Conclusion
To sum up, when looking to choose between the BSUN Guyu linear switch and the Aflion Iceberg linear switch, you should consider the key features that align with your preferences. If you value a unique auditory experience with a medium weight, super-smooth keystrokes, and a distinctive sound signature that combines depth and clarity, the Guyu switch may be the perfect choice for you. On the other hand, if you prefer a satisfying smoothness, a fulfilling feel due to a two-stage spring, and switches that are relatively new but still exhibit high quality, then the Iceberg switch could be more suited to your taste. Ultimately, your decision should be based on whether you prioritize the auditory experience and feel of the Guyu switch or the smoothness and innovative design of the Iceberg switch.
