Gateron CJ vs. KTT Purple Star
An in-depth look at the Gateron CJ and the KTT Purple Star switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, two popular options to consider are the Gateron CJ and the KTT Purple Star, both of which are linear switches. The CJ is praised for its unique and enjoyable presentation of a linear switch, characterized by higher-pitched clacks and an incredibly smooth push feel. On the other hand, the Purple Star stands out for its all-POM construction, providing a buttery smooth typing experience with a neutral sound signature and a very light 45g bottom-out, perfect for those who prefer easier key presses. Each switch offers its own set of qualities, making them appealing for different preferences. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The Gateron CJ and the KTT Purple Star both feature POM top housings, which create a unique and pleasing sound profile that is deeper and relatively more muted compared to other materials. This results in a more satisfying typing experience for those who prefer a quieter sound. However, the CJ uses a proprietary INK blend for its top housing, which is characterized by a slightly higher-pitched and clacky sound profile. This difference may appeal to users who prefer a crisper and sharper sound when typing.
When it comes to the bottom housing, both the CJ and the Purple Star utilize POM material, which contributes to the overall sound profile of the switch. The deeper sound and muted qualities of POM housing create a more subdued typing experience, which can be preferred by those who work in quiet environments or simply enjoy a more subtle sound while typing. The bottom housing plays a significant role in the bottom-out sound and feel of a switch, so having POM material in this part of the switch can provide a consistent typing experience.
Overall, despite the differences in the top housing material between the Gateron CJ and the KTT Purple Star, both switches offer a unique sound profile that is characterized by the qualities of POM material. Whether you prefer the slightly higher-pitched and clacky sound of the CJ's proprietary INK blend top housing or the deeper and more muted sound of the Purple Star's POM top housing, both switches provide a satisfying typing experience. The use of POM material in the bottom housing further enhances the overall sound profile of each switch, creating a consistent and pleasant typing experience for users.
Weight
When comparing the actuation force and bottom out force of the Gateron CJ linear switch and the KTT Purple Star linear switch, it is evident that the CJ has a heavier actuation force of 50 grams compared to the Purple Star's lighter actuation force of 43 grams. Additionally, the CJ also has a higher bottom out force of 60 grams, while the Purple Star has a lower bottom out force of 50 grams. This means that the CJ linear switch provides a more substantial typing experience with a stronger push feel, which some users may prefer for a more tactile typing experience. On the other hand, the lighter actuation force and bottom out force of the Purple Star switch make it ideal for users who prefer a lighter touch and want to type for longer periods without experiencing fatigue. Overall, the actuation and bottom out forces of these switches cater to different preferences, with the CJ being heavier and the Purple Star being lighter, providing users with options based on their individual typing preferences.
Travel distance
Comparing the travel distance of the Gateron CJ linear switch and the KTT Purple Star linear switch, the CJ has a longer travel distance of 4 mm, while the Purple Star has a slightly shorter travel distance of 3.5 mm. The CJ's 4.0mm travel distance offers a more traditional typing experience, providing a deeper key press feel compared to the Purple Star's 3.5 mm travel distance. Gamers looking for faster response times may prefer the shorter travel distance of the Purple Star, while those who enjoy a more substantial keypress may lean towards the CJ. Ultimately, the choice between the two switches depends on personal preference for travel distance and keypress feel.

However, the Purple Star switch stands out with its easy-to-press feature, providing minimal resistance during key presses and reducing finger fatigue during extended typing sessions. In contrast, the CJ switch does not have a specific descriptor for easy-to-press, indicating that it may have a slightly different feel in terms of responsiveness and actuation force.
In conclusion, the Gateron CJ linear switch and the KTT Purple Star linear switch have their own unique qualities in terms of sound and feel.

In closing, when deciding between the Gateron CJ linear switch and the KTT Purple Star linear switch, consider your preference for bottom-out force and typing experience. If you prefer a medium bottom-out force and enjoy a unique, higher-pitched sound with a smooth push feel, the Gateron CJ switch may be the right choice for you. On the other hand, if you prefer a lighter bottom-out force and prioritize a buttery smooth typing experience with a neutral sound signature, the KTT Purple Star switch may be more suitable for your needs. Ultimately, your decision should be based on your individual typing preferences and desired sensory experience.
