SP-Star RedBlue vs. Gazzew U4Tx
An in-depth look at the SP-Star RedBlue and the Gazzew U4Tx switches—which one is the best fit for you?
Overview
Introducing two remarkable mechanical keyboard switches, the SP-Star RedBlue and the Gazzew U4Tx, which offer distinct typing experiences. The RedBlue, a linear switch, is perfect for those in search of a medium-light key press. It exhibits a relatively higher-pitched sound profile and falls under the categories of being low-pitched, neutral, mild, thocky, and polished. On the other hand, the U4Tx, a tactile switch, combines the best of both worlds, providing a refined sound profile. With a deep, resonant "thock" when bottoming out and a whisper-quiet stealth when topping out, each press offers a sharp and satisfying tactile bump. Categorized as bassy, muted, and sharp, the U4Tx ensures a luxurious and acoustically pleasing typing experience. However, let's dive in a bit deeper beyond generalities so you can best decide on the ideal switch for your preferences.

Housing materials
The housing materials of the SP-Star RedBlue and the Gazzew U4Tx switches differ in terms of their sound profiles. The RedBlue utilizes polycarbonate for both the top and bottom housing, resulting in a sharper, higher-pitched, and crisper sound. The stiffness of polycarbonate contributes to a clear and resonant sound, making it ideal for RGB lighting due to its translucency. In contrast, the U4Tx features Gazzew's proprietary plastic blend, known as "boba plastic," for both the top and bottom housing. This unique blend delivers a rich and deep sound profile due to its softness. Consequently, the RedBlue's polycarbonate housing offers a more distinct and bright sound, while the U4Tx's Gazzew blend provides a deeper and more soothing sound experience.
While the housing materials of the RedBlue and U4Tx differ, they both offer distinct advantages. The polycarbonate top housing of the RedBlue excels in producing a sharper and crisper sound, making it a popular choice for users seeking a more precise typing experience. Additionally, its translucency is ideal for those utilizing RGB lighting effects. In comparison, the Gazzew blend top housing of the U4Tx creates a rich and deep sound that offers a more soothing and immersive typing experience. This proprietary blend, often referred to as "boba plastic," provides a unique tactile feel that may appeal to users looking for a softer keypress.
When it comes to the bottom housing, the materials of the RedBlue and U4Tx share similar impacts on the overall typing experience. The bottom housing influences the bottom-out sound and feel when pressing down on the switch. Both the polycarbonate and Gazzew blend bottom housings contribute to the sound and tactile feedback experienced when fully depressing a key. Therefore, users can expect comparable results in terms of the impact and sensation during bottom-out with either the RedBlue or U4Tx switches, irrespective of their respective top housing materials.
In summary, the housing materials of the SP-Star RedBlue and Gazzew U4Tx switches differ in their sound profiles. The RedBlue's polycarbonate top and bottom housings produce a sharper and crisper sound, while the U4Tx's Gazzew blend top and bottom housings deliver a rich and deep sound. However, users will still experience similar results in the overall typing experience when it comes to the bottom housing of both switches. Ultimately, the choice between the two would depend on individual preference for either a more precise and bright sound (RedBlue) or a softer and immersive sound (U4Tx).
Weight
When comparing the actuation force and bottom out force of the SP-Star RedBlue linear switch and the Gazzew U4Tx tactile switch, there are a few distinctions to note. The actuation force of both switches is currently unavailable, but their bottom out forces provide some insight. The RedBlue has a bottom out force of 57 grams, which falls into the medium-light range. On the other hand, the U4Tx has a bottom out force of 65 grams, placing it in the medium-heavy category.
Considering weight is important for different reasons. Some prefer lighter switches as it allows them to type for extended periods, making it ideal for work or long gaming sessions. For these individuals, the RedBlue switch may be a suitable choice due to its medium-light bottom out force. However, there are those who desire a stronger push feel for a more substantial typing experience. These individuals should opt for switches with heavier forces. In this scenario, the U4Tx switch may be more preferable with its medium-heavy bottom out force of 65 grams.
While the actuation forces of both switches are unknown, it is likely that they are within a similar range, as switches with similar bottom out forces often have comparable actuation forces as well. Therefore, even though we don't have specific data for the actuation forces, the RedBlue and U4Tx switches are likely to provide similar actuation experiences. In terms of weight, the RedBlue is lighter than the U4Tx, making it more suitable for those seeking a lightweight typing experience, whereas the U4Tx is heavier and caters to individuals who prefer a stronger push feel.
Travel distance
When comparing the travel distance of the SP-Star RedBlue linear switch and the Gazzew U4Tx tactile switch, there is a clear distinction. The RedBlue switch has a travel distance of 4 mm, which falls into the more traditional range. On the other hand, the U4Tx switch has a slightly shorter travel distance of 3.6 mm. The RedBlue switch provides a deeper press, which can be preferred by those who enjoy a more substantial feel when typing. In contrast, the U4Tx switch offers a shallower press, which some gamers might find advantageous for faster response times. Ultimately, the choice between these switches depends on personal preference. If you value responsiveness, the U4Tx with its shorter travel distance might be your best bet. However, if you prefer a more satisfying depth to your key presses, the RedBlue switch with its slightly longer travel distance would suit you better.
