Housing materials

The housing materials used in the SP-Star Polaris Gray and the Gazzew U4Tx keyboards offer distinct differences in sound profiles. The Polaris Gray utilizes polycarbonate for both its top and bottom housings. The stiffness of polycarbonate gives the switch a sharper and crisper sound profile, resulting in a higher-pitched tone. This material is especially effective in the top housing, where it enhances the resonant and clear sound when keys are released. Furthermore, the translucency of polycarbonate allows for RGB lighting, adding an aesthetically pleasing element to the keyboard.

In contrast, the Gazzew U4Tx employs a proprietary Gazzew blend for both the top and bottom housings. This unique plastic blend, often referred to as "boba plastic," offers a softer texture and creates a rich and deep sound profile. The softness of the material contributes to a more satisfying bottom-out sound and feel when pressing down on the keys. The U4Tx's Gazzew blend top housing ensures that the key release sound maintains its desirable depth and resonance.

Despite their differences, both switches deliver impressive acoustic experiences. While the Polaris Gray's polycarbonate housing produces a sharper and crisper sound, the Gazzew U4Tx's proprietary blend offers a rich and deep tone. Whether you prefer the high-pitched clarity of the Polaris Gray or the deep resonance of the U4Tx, both switches deliver satisfying sound profiles for enthusiastic mechanical keyboard users.

In summary, the choice between the SP-Star Polaris Gray and the Gazzew U4Tx housing materials ultimately comes down to personal preference. The polycarbonate housing of the Polaris Gray provides a sharper and crisper sound, ideal for those seeking a higher-pitched tone. Conversely, the proprietary Gazzew blend used in the U4Tx offers a softer texture and a rich, deep sound profile, catering to those who prefer a more satisfying bottom-out experience. Regardless of the chosen switch, both options ensure a delightful acoustic journey for mechanical keyboard enthusiasts.

Weight

When comparing the actuation force and bottom out force of the SP-Star Polaris Gray linear switch and the Gazzew U4Tx tactile switch, both switches have an unavailable actuation force. This means that the force required to trigger a keystroke is unknown for both switches. However, the Polaris Gray has a bottom out force of 67 grams, which can be considered medium-heavy, while the U4Tx has a slightly lower bottom out force of 65 grams, also classified as medium-heavy.

Considering weight, the lighter option is typically favored by individuals who value longer typing sessions, making it suitable for work keyboards or extended gaming sessions. In this case, since both switches have an unknown actuation force, it is difficult to determine which one is lighter. However, based on the bottom out force comparison, it can be assumed that the U4Tx may be slightly lighter due to its 65-gram bottom out force, compared to the Polaris Gray's 67-gram bottom out force.

On the other hand, for those who prefer a stronger push feel and a more substantial typing experience, options with heavier forces are more appropriate. Both the Polaris Gray and U4Tx fall into the medium-heavy range, making them suitable for individuals seeking a satisfying keystroke that requires a bit more force to bottom out.

In summary, while the actuation force is unavailable for both switches, the Polaris Gray has a slightly higher bottom out force of 67 grams compared to the U4Tx's 65 grams. This suggests that the Polaris Gray may provide a slightly heavier typing experience. However, since both switches fall into the medium-heavy range, individuals seeking a more substantial typing experience can expect similar results from either option.

Travel distance

The SP-Star Polaris Gray linear switch has a travel distance of 4.0 mm, while the Gazzew U4Tx tactile switch has a slightly shorter travel distance of 3.6 mm. Both switches provide a noticeable distance when pressed, allowing users to feel the keystroke. The Polaris Gray's 4.0 mm travel distance is more in line with traditional switch distances, while the U4Tx's 3.6 mm is on the shallower side. Shorter travel distances, such as the U4Tx, are often preferred by gamers who prioritize faster response times. On the other hand, some individuals may find shorter travel distances to feel too abrupt and prefer the gentle depth provided by the Polaris Gray's longer travel distance. Ultimately, the choice between these switches depends on personal preference and the desired typing or gaming experience.
