Housing materials
In comparing the housing materials of the Outemu Dustproof Blue and the KTT Purple Star, it is clear that both switches offer unique sound profiles due to their different top housings. The Dustproof Blue's polycarbonate top housing creates a sharper, higher-pitched sound profile compared to the deeper and more muted sound produced by the Purple Star's POM top housing. Additionally, the Dustproof Blue's translucent polycarbonate housing is ideal for RGB lighting, making it a visually appealing choice for those looking to customize their keyboard setup.
When it comes to the bottom housings, both switches offer distinct qualities that contribute to the overall typing experience. The Dustproof Blue's nylon bottom housing produces a deeper and fuller sound profile, thanks to its softer plastic construction that absorbs more sound. Conversely, the Purple Star's POM bottom housing also creates a deep and muted sound profile, offering a different tactile sensation compared to the Dustproof Blue. Despite these differences, both bottom housings enhance the overall sound quality of the switches in their own unique ways.
Overall, while the top and bottom housings of the Outemu Dustproof Blue and the KTT Purple Star differ in material and sound profile, both switches provide a satisfying typing experience. Whether you prefer the sharper, crisper sound of the Dustproof Blue's polycarbonate top housing or the deeper, more muted sound of the Purple Star's POM top housing, both switches offer unique qualities that cater to different preferences. Similarly, the nylon and POM bottom housings of each switch contribute to the overall typing experience, ensuring that users can enjoy a variety of sound profiles based on their personal preferences.
Weight
The Outemu Dustproof Blue clicky switch has a higher actuation force of 50 grams compared to the KTT Purple Star linear switch's 43 grams, making it slightly heavier. In terms of bottom out force, the Dustproof Blue requires 65 grams of force, while the Purple Star only needs 50 grams, making the Dustproof Blue heavier in this aspect as well. These differences mean that the Dustproof Blue will provide a more substantial typing experience with a stronger push feel, ideal for those who prefer a bit more resistance. On the other hand, the Purple Star will be lighter and easier to type on for longer periods, making it a great choice for those looking for a more comfortable typing experience. Ultimately, the choice between the two switches will depend on personal preference for actuation and bottom-out forces.
Travel distance
The travel distance of the Outemu Dustproof Blue clicky switch is 4 mm, while the KTT Purple Star linear switch has a travel distance of 3.5 mm. In this case, the Purple Star has a shorter travel distance compared to the Dustproof Blue. Generally, a shorter travel distance is favored by gamers for quicker response times, while a longer travel distance may provide a more satisfying tactile feedback. Both switches offer slightly different typing experiences due to their varying travel distances, so it ultimately comes down to personal preference. If you're looking for a quicker response time, the Purple Star may be the better option, but if you prefer a more pronounced keypress feel, the Dustproof Blue might be more suitable.

Typing experience
