Aflion Blue Sky vs. Gazzew U4Tx RGB

Overview

When choosing between mechanical keyboard switches, the Aflion Blue Sky and the Gazzew U4Tx RGB each offer unique experiences tailored to different typing preferences. The Blue Sky switches are celebrated for their crystal-clear linear action, characterized by a smooth push feel and a high-pitched, sparkling sound profile that enhances the typing experience for those who favor rapid keystrokes without any tactile feedback. On the other hand, the Gazzew U4Tx RGB switches provide a tactile sensation with their pronounced bump, combining a rich "thock" sound upon bottoming out and a quiet top-out, making them ideal for users who appreciate a luxurious typing experience with auditory cues. Ultimately, the decision comes down to your preferred typing style: whether you prioritize effortless linear movement or the tactile engagement of a well-defined bump. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials

The Aflion Blue Sky and the Gazzew U4Tx RGB both utilize distinct housing materials that significantly influence their sound profiles, although they diverge in composition and acoustic properties. The Blue Sky's polycarbonate top housing is noted for creating a sharper, crisper sound due to its stiffness, which enhances clarity and resonance. This characteristic makes it particularly suited for RGB lighting, as its translucency allows for a vibrant and noticeable illumination effect. In contrast, the U4Tx RGB employs a proprietary Gazzew blend, often referred to as "boba plastic," for its top housing. This material tends to deliver a softer sound profile, providing a deeper and richer tonal experience, which can result in softer keystrokes but lacks the crispness of polycarbonate.

The bottom housings of the two switches present a similar juxtaposition of characteristics, but they also bear a notable commonality. The Blue Sky features a nylon bottom housing known for producing a fuller, more resonant sound profile due to its softer texture that absorbs sound effectively. This results in a duller and rounder auditory experience when typing. Likewise, the U4Tx RGB employs the same proprietary Gazzew blend for its bottom housing, maintaining the soft quality that contributes to its overall rich sound profile. Despite their differing top materials, both switches achieve a depth of sound through their soft bottom housing, suggesting that they may produce similar auditory outcomes even if the styles vary.

When it comes to the overall typing experience, the differences in top and bottom housing materials explain how each switch can create a unique auditory profile. The Aflion Blue Sky leverages the bright clarity of polycarbonate in its top housing to enhance the sharpness of released sounds, while the U4Tx RGB relies on the soft qualities of its proprietary blend to create a warmer tonal output. Since the bottom housing affects the bottom-out sound and feel of the switch while the top housing influences the sound upon release, a skilled typist may achieve desirable results from either switch by understanding the acoustic properties at play. Although the two switches differ in their material compositions, their sound profiles can converge, providing a rich typing experience through the softness inherent in both switches’ bottom housings.

Weight

When comparing the Aflion Blue Sky linear switch and the Gazzew U4Tx RGB tactile switch, we can observe notable differences in their actuation and bottom out forces. The Blue Sky switch features an actuation force of 50 grams and a bottom out force of 60 grams, positioning it as a medium-force option suitable for those who seek a balanced typing experience. In contrast, the Gazzew U4Tx RGB switch does not specify an actuation force, which leaves it unknown, but it does have a bottom out force of 65 grams, categorizing it as medium-heavy. This makes the U4Tx RGB heavier in terms of bottoming out compared to the Blue Sky. As a result, users who prefer a lighter touch for longer typing sessions might gravitate towards the Aflion Blue Sky, while those who enjoy a firmer push and more substantial feedback should consider the Gazzew U4Tx RGB for their needs. Overall, while the Blue Sky offers a more moderate typing effort, the Gazzew switch presents a heavier resistance at bottoming out.

Travel distance

When comparing the travel distances of the Aflion Blue Sky linear switch and the Gazzew U4Tx RGB tactile switch, a notable distinction emerges. The Aflion Blue Sky has a travel distance of 4 mm, while the Gazzew U4Tx RGB features a shorter travel distance of 3.6 mm. This difference means that the Blue Sky offers a more traditional feel, which some users may find preferable for its hearty depth and tactile feedback. In contrast, the U4Tx RGB caters to those who favor quicker response times, aligning with the trend of shorter travel distances favored by many gamers. Consequently, if you prioritize a swift, responsive experience, the U4Tx RGB would be the better choice, whereas the Blue Sky may be more suitable for users who appreciate a more substantial key press. Overall, the Aflion Blue Sky is the longer travel option, while the Gazzew U4Tx RGB is the shorter.

Price comparison

Typing experience

The sound profile of the Aflion Blue Sky linear switch is characterized by a sparkling quality, producing a high-pitched and crisp audio experience upon actuation. This can appeal to users who prefer a sharper sound over the deeper, richer tones commonly associated with other switches. In contrast, the Gazzew U4Tx RGB tactile switch offers a distinct sound signature, known for its deep "thock" when bottoming out, complemented by the quiet ascent of the U4 topping out. Since the U4Tx RGB's sound profile combines both refined and bassy characteristics, it provides a luxurious auditory experience that may be preferred in quieter environments, especially where minimal noise is desired.

When it comes to the feel of the switches, the Blue Sky linear is noted for its mild characteristics, offering a gentle and approachable typing experience that caters well to all users, whether beginners or experienced typists. Its polished nature ensures that key presses are smooth and refined, resulting in reduced friction and an effortlessly fluid action. On the other hand, the Gazzew U4Tx RGB tactile switch incorporates a sharp tactile bump, creating a satisfying feedback sensation with each press. However, details of its overall smoothness and potential for friction reduction aren't specified, leaving its exact feel somewhat ambiguous in comparison.

In summary, the Aflion Blue Sky switch is ideal for those who prioritize a high-pitched, clear sound and a smooth, mild typing feel, making it accessible for users of all experience levels. In contrast, the Gazzew U4Tx RGB offers a unique blend of deep thock and tactile feedback, aimed at those who seek a rich auditory and tactile experience. While both switches provide quality feel and sound, your choice will ultimately depend on your preference for sound profile and tactile feedback. If you're looking for overall satisfaction in your typing experience, either switch can deliver remarkable results based on their distinct offerings.

Conclusion

To conclude, your choice between the Aflion Blue Sky linear switch and the Gazzew U4Tx RGB tactile switch should hinge on your personal preferences and intended use. If you prioritize a smooth and fast typing experience, the Blue Sky's medium bottom out force of 60 grams, along with its long pole stem, is ideal for you, providing a crystal-clear linear feel that's perfect for fast-paced typing or gaming. Its high-pitched sound profile ensures a lively auditory feedback without being overwhelming, making it suitable for both home and office environments, especially if quiet is not a primary concern. On the other hand, if you enjoy a more tactile experience and deep sound when typing, the U4Tx RGB offers a luxurious "thock" along with its medium-heavy resistance of 65 grams. The tactile bump and refined sound profile contribute to a satisfying feedback loop that many typists find rewarding. Therefore, if you're looking for a switch that combines rich auditory feedback with a noticeable tactile experience, the U4Tx RGB is the way to go. In essence, your decision should reflect whether you prioritize speed and smoothness or tactile feedback and sound quality during your typing sessions.
