Housing materials

The SP-Star Polaris Purple and KTT Purple Star keyboards both offer unique housing materials that contribute to the overall sound profile of the switches. The Polaris Purple features a polycarbonate top housing, known for creating a sharper, higher-pitched sound profile, while the Purple Star utilizes a POM top housing, which produces a deeper and more muted sound. This contrast in sound profiles can greatly affect the typing experience for users, with the Polaris Purple offering a more crisp and resonant sound compared to the Purple Star's softer and more subdued tone.

In terms of bottom housing, both the SP-Star Polaris Purple and KTT Purple Star keyboards showcase similar differences in material. The Polaris Purple includes a polycarbonate bottom housing, which contributes to a sharper and clearer sound profile, while the Purple Star boasts a POM bottom housing that offers a deeper and more muted sound. These contrasting sound profiles between the bottom housings of the two keyboards can impact the overall typing experience, with the Polaris Purple providing a more resonant bottom-out sound compared to the Purple Star's softer touch.

Despite the differences in housing materials between the SP-Star Polaris Purple and KTT Purple Star keyboards, they both offer unique sound profiles that cater to different preferences. While the Polaris Purple's polycarbonate housing material produces a sharper and crisper sound, the Purple Star's POM housing material offers a deeper and more muted tone. Ultimately, the choice between the two keyboards will come down to individual preference for sound profile, with the Polaris Purple providing a more vivid and resonant typing experience, while the Purple Star offers a softer and more subdued sound.

Weight

The SP-Star Polaris Purple tactile switch and the KTT Purple Star linear switch have significant differences in their actuation and bottom out forces. The Polaris Purple has a medium-heavy bottom out force of 67 grams, while the Purple Star has a lighter bottom out force of 50 grams. The actuation force of the Polaris Purple is unknown, while the Purple Star has an actuation force of 43 grams. This means that the Purple Star requires less force to trigger a keystroke compared to the Polaris Purple. For those who prefer a lighter typing experience, the Purple Star would be the more suitable option, allowing for longer periods of typing without experiencing fatigue. On the other hand, the Polaris Purple is better suited for individuals who prefer a stronger push feel and a more substantial typing experience.
