Aflion Iceberg vs. Gazzew U4Tx

Overview

When it comes to mechanical keyboard switches, the Aflion Iceberg and the Gazzew U4Tx both offer unique characteristics that cater to different preferences. Aflion, although a relatively new switch manufacturer, has made quite the impression with their Iceberg switches. Known for their smoothness and satisfying feel, these linear switches are categorized as clacky, high-pitched, snappy, feathery, and subtle. On the other hand, the Gazzew U4Tx switches blend the best of both worlds, providing a refined sound profile that combines the deep, resonant "thock" of the U4T when bottoming out and the whisper-quiet stealth of the U4 when topping out. With a sharp, satisfying tactile bump, these tactile switches deliver a luxurious typing experience. However, let's dive in a bit deeper beyond generalities so you can best decide on the perfect switch for you.

Housing materials

The housing materials of the Aflion Iceberg and the Gazzew U4Tx differ significantly. The Iceberg utilizes a polycarbonate top housing, which results in a sharper, higher-pitched, and crisper sound profile. This is due to polycarbonate being a stiffer plastic, allowing for a clearer and more resonant sound. Additionally, the polycarbonate's translucency makes it particularly advantageous when using RGB lighting. In contrast, the U4Tx features a proprietary Gazzew blend top housing, sometimes called "boba plastic," which produces a rich and deep sound profile. Its softness contributes to the sound's depth and richness.

Regarding the bottom housing, the Iceberg employs a nylon material known for creating a deeper and fuller sound profile. Nylon's softness absorbs more sound compared to harder plastics, resulting in a duller and rounder sound. On the other hand, the U4Tx incorporates Gazzew's proprietary blend for the bottom housing, referred to as "boba plastic." Like the top housing, this blend offers a softness that contributes to a rich and deep sound.

Despite their differences, both switches demonstrate how the top and bottom housings impact the overall sound and feel. When pressing down on either switch, the qualities of the respective bottom housing become evident as they greatly influence the bottom-out sound and feel. Conversely, the top housing's impact becomes more apparent when releasing a key. In this aspect, both switches share a similarity in how the top housing affects the sound produced when letting go of a key.

Weight

When comparing the actuation force and bottom out force of the Aflion Iceberg linear switch and the Gazzew U4Tx tactile switch, several differences become apparent. The Iceberg switch has a relatively light actuation force of 37 grams, meaning it requires a relatively small amount of force to trigger a keystroke. In contrast, the U4Tx switch's actuation force is unavailable, making it difficult to directly compare. However, the Iceberg switch has a bottom out force of 45 grams, which is lighter than the U4Tx's bottom out force of 65 grams, indicating that the U4Tx switch requires a stronger push to fully press the key.

Considerations of weight play a significant role in switch preference. Some individuals prefer lighter switches to allow for longer typing periods, making them ideal for work or extended gaming sessions. On the other hand, individuals seeking a more substantial typing experience may prefer switches with heavier forces, which provide a stronger push feel. While the Iceberg switch falls on the lighter side, offering a comfortable actuation force for longer usage, the U4Tx switch's higher bottom out force caters to those seeking a more tactile and substantial typing experience. Therefore, the two switches differ in their weight characteristics and cater to different preferences.

Travel distance

The Aflion Iceberg linear switch and the Gazzew U4Tx tactile switch have different travel distances. The Iceberg has a travel distance of 4 mm, while the U4Tx has a travel distance of 3.6 mm. The Iceberg's travel distance is slightly longer than the U4Tx, making it the switch with more depth in its keystrokes. In general, a travel distance of 4mm is considered more traditional, offering a satisfying amount of key depth. On the other hand, the U4Tx's 3.6mm travel distance falls on the shallower end, which may be preferred by gamers or those looking for quicker response times. Ultimately, the choice between the two switches will depend on personal preference for depth and responsiveness.

Typing experience

When it comes to sound, the Iceberg linear switch from Aflion is known for its clacky and high-pitched characteristics. Pressing these switches produces a sharp and snappy sound that is crisp, bright, and percussive. On the other hand, the Gazzew U4Tx tactile switch offers a completely different sound profile. These switches marry the best of both worlds, providing a deep, resonant "thock" when bottoming out, combined with a whisper-quiet sound when topping out. The U4Tx switches produce a bassy and muted sound, offering a richer and softer sound experience compared to the Iceberg. It's important to note that the sound of a switch is also influenced by factors such as the keyboard board and keycaps used.

Moving on to feel, the Iceberg switch is described as having a snappy and feathery feel. The longer or dual-staged springs in these switches contribute to their super responsiveness, making the typing experience feel alive. Additionally, the Iceberg provides a light actuation force that reduces finger fatigue and strain, making it comfortable for extended sessions of typing, gaming, school, or work. These switches also have a subtle resistance, maintaining a light typing feel, and the sound signature is not resonant, making them suitable for shared spaces.

In contrast, the Gazzew U4Tx tactile switch offers a sharp tactile bump with high feedback intensity. Each keypress is accompanied by a prominent and distinct tactile feedback, providing an enhanced typing experience. Unfortunately, further information on the feel of the U4Tx switch is not provided.

Based on the available information, the Iceberg linear switch and the Gazzew U4Tx tactile switch offer distinct qualities in terms of sound and feel. The Iceberg produces a clacky and high-pitched sound, with a snappy, feathery, and subtle feel. On the other hand, the U4Tx offers a bassy and muted sound, along with a sharp tactile bump for a heightened typing experience. While there may be similarities in certain aspects, such as the satisfying feel both switches aim to provide, it is important to consider individual preferences and personal typing requirements when choosing between these two switches.

Conclusion

In closing, if you prioritize a light and smooth typing experience with a satisfying feel, the Aflion Iceberg linear switch would be a great choice for you. With its bottom out force of 45 grams, it offers a feathery and snappy feel that reduces finger fatigue and provides a comfortable typing experience. Additionally, the Iceberg switch produces a clacky and high-pitched sound profile, giving you a sharp and crisp sound when typing.

On the other hand, if you prefer a tactile switch with a cleaner and refined sound profile, the Gazzew U4Tx tactile switch would be a better fit. With its bottom out force of 65 grams, the U4Tx offers a sharp and satisfying tactile bump, providing a luxurious and acoustically pleasing typing experience. Moreover, the U4Tx switch produces a bassy and muted sound profile, offering a deeper and richer sound during key presses while minimizing noise.

Ultimately, the choice between the Aflion Iceberg linear switch and the Gazzew U4Tx tactile switch depends on your preference for typing feel and sound. Consider your priorities and preferences to make the best decision for your mechanical keyboard setup.
