Gateron CJ vs. HMX EVA
An in-depth look at the Gateron CJ and the HMX EVA switches—which one is the best fit for you?
Overview
When it comes to choosing a mechanical keyboard switch, the Gateron CJ and the HMX EVA stand out as exceptional options for linear switch enthusiasts, each offering distinct characteristics that cater to different typing preferences. The Gateron CJ is celebrated for its enjoyable auditory feedback, providing a higher-pitched clack that many users find delightful, along with its remarkably smooth push feel. Its sound profile is a unique blend of chirpy and neutral tones, making it compelling for those who appreciate a little acoustic flair in their typing experience. On the other hand, the HMX EVA boasts a design inspired by the iconic colors of Evangelion Unit-01, promising a resonant sound signature that adds a layer of depth to the typing experience, all while maintaining a silky smooth feel that many users crave. Both switches offer a satisfying linear experience, but the choice between them will greatly depend on your personal style and preferences. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
When comparing the housing materials of the Gateron CJ and the HMX EVA, it is important to note the distinct constructions employed by each. The Gateron CJ features a proprietary INK blend for its top housing, which lends itself to a pointed, higher-pitched sound profile that many users describe as clacky. Conversely, the HMX EVA utilizes nylon for its top housing, which is known for producing a deeper and fuller sound profile due to nylon's softer nature. This inherent difference in top housing materials leads to varied auditory experiences; while the CJ may appeal to those who prefer a crisp sound, the EVA caters to those who appreciate a more muted and rounded auditory feedback.
Moving to the bottom housings, the contrasts continue. The Gateron CJ incorporates a POM bottom housing that results in a unique sound profile that is deeper and more muted, thus complementing its sharper top housing. In contrast, the HMX EVA also employs nylon for its bottom housing, amplifying the already deep and rounded sound profile established by its top housing. This means that while both switches employ materials that contribute to deeper sounds, the CJ aims for a blend of qualities by utilizing different materials for each section, whereas the EVA maintains a uniformity in its nylon construction for both top and bottom. The presence of POM in the CJ's bottom housing means that the switch's bottom-out sound will have a distinctive character that may not be replicated by the EVA.
When pressed, the characteristics of the switch materials come into play. The Gateron CJ’s sound experience is largely defined by how the top housing’s INK blend interacts with the POM bottom housing, creating a striking contrast between the higher-pitched release and the muted bottom-out. The EVA, on the other hand, delivers a more consistent sound profile with both top and bottom made from nylon, leading to a cohesive typing experience. Therefore, while users may enjoy different tonal qualities and tactile feedback from each switch, the usage of varying materials points toward a deeper customization of sound and feel, with each type catering to specific preferences within the mechanical keyboard community. Thus, while both switches can elicit satisfying results in terms of auditory feedback, their differing material compositions contribute to unique experiences that distinguish their overall performance.
Weight
When comparing the Gateron CJ linear switch and the HMX EVA linear switch, there are notable differences in both actuation force and bottom out force. The Gateron CJ requires a higher actuation force of 50 grams and has a bottom out force of 60 grams, making it a medium-weight switch. In contrast, the HMX EVA boasts a lighter actuation force of 42 grams and a bottom out force of 48 grams, categorizing it as a light switch. This weight difference may influence user experience; those who favor a softer touch and lighter typing feel may gravitate towards the EVA, while users who prefer a more substantial push during typing may opt for the heavier CJ. Ultimately, if you're looking for a switch that feels more robust, the Gateron CJ would be your choice, while the HMX EVA is better suited for extended use without fatigue.
Travel distance
The Gateron CJ linear switch features a travel distance of 4 mm, while the HMX EVA linear switch has a shorter travel distance of 3.6 mm. This difference highlights the contrasting design philosophies behind the two switches; the CJ, with its traditional 4 mm distance, may provide a more pronounced tactile experience, appealing to those who enjoy a deeper keypress. In contrast, the EVA's 3.6 mm travel distance caters to gamers and individuals seeking quicker response times, making it a suitable choice for fast-paced gameplay. Essentially, if you're looking for a more responsive keypress, the HMX EVA would be the better option, while the Gateron CJ is ideal for those who appreciate a fuller depth in their switch travel.

Typing experience
When it comes to sound, the Gateron CJ switch stands out with its unique acoustic signature, described as chirpy and thocky. This means that while it produces a higher-pitched clack reminiscent of a light squeak, it also delivers a deeper, rich sound that can satisfyingly echo like a soft "thud" on actuation. This contrast makes it versatile, catering to a variety of environments from home offices to casual gaming. The EVA switch, however, lacks a detailed sound description, which leaves its exact acoustic profile unknown. However, given its resonant sound signature, it suggests a different auditory experience than the CJ’s higher pitch, potentially offering a more distinct tone that might appeal to fans of themed designs.
In terms of feel, the CJ is characterized by a mild switch experience, which means it offers a gentle typing sensation that is approachable for most users. This quality makes them suitable for both beginners and experienced typists, as their smooth operation does not overwhelm the user. The EVA's tactile or smooth feel is not specified, leaving its performance in this category uncertain. Nevertheless, the smoothness implied in its description might suggest a pleasant typing experience akin to Gateron's known linear qualities.
In conclusion, both the Gateron CJ and HMX EVA switches offer unique experiences, especially in sound and feel. The CJ provides a recognizable sonic profile that combines chirpy and thocky elements with its mild touch, making it appealing for a broad range of users. While the EVA’s sound and feel remain less defined, its design inspiration hints at a distinctive character that might resonate with specific preferences. Ultimately, those seeking either switch can expect smooth functionalities, though they will likely gravitate towards the CJ for its well-rounded, enjoyable auditory and tactile feedback.
Conclusion
To conclude, choosing between the Gateron CJ linear switch and the HMX EVA linear switch ultimately depends on your personal preferences and typing style. If you enjoy a switch that provides a more robust feedback with a deeper sound profile, and you're comfortable with a medium bottom-out force of 60 grams, the Gateron CJ is an excellent choice. Its unique chirpy and thocky sound, blended with an impossibly smooth feel, creates a distinct typing experience that can be both engaging and satisfying. On the other hand, if you prefer a lighter touch while typing, and value a smoother and more resonant sound, the HMX EVA with a lighter bottom-out force of 48 grams would be better suited for you. The EVA's design, inspired by the colors of Evangelion Unit-01, offers a silky typing sensation that can enhance your productivity without feeling overly taxing on your fingers. Therefore, consider your typing habits and the acoustic feedback you desire to make the best decision for your mechanical keyboard experience.
