Gateron CM vs. Outemu Purple
An in-depth look at the Gateron CM and the Outemu Purple switches—which one is the best fit for you?
Overview
When comparing the Gateron CM, a linear switch, with the Outemu Purple, a tactile switch, there are some distinct differences to consider. The CM switch sets itself apart by featuring a full nylon housing, providing a richer sound and smoother typing experience thanks to its factory lube job. With a dual-staged spring, typing on the CM switch offers a bouncy sensation that feels effortless. On the other hand, the Outemu Purple switch lacks specific standout features but falls into the tactile category, offering a different typing experience compared to the CM. While the CM switch is described as 'Buttery', 'Bassy', 'Polished', 'Thocky', 'Low-pitched', 'Creamy', and 'Frictionless', the Purple switch does not have any specific descriptors. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The housing materials of the Gateron CM and the Outemu Purple switches differ significantly in terms of the material used. The CM features a nylon top housing, while the Purple uses a polycarbonate top housing. This contrast leads to a noticeable difference in sound profiles when typing on the switches. The nylon top housing of the CM produces a deeper and fuller sound, thanks to its softer plastic that absorbs more sound. In contrast, the polycarbonate top housing of the Purple creates a sharper, higher-pitched, and crisper sound due to its relatively stiffer plastic composition. Additionally, the translucency of polycarbonate makes it ideal for RGB lighting effects, adding an aesthetic appeal to the switch.
On the other hand, despite the differences in top housing materials, both the Gateron CM and the Outemu Purple switches share a nylon bottom housing. This commonality means that when typing on either switch, users can expect a deeper and fuller sound profile due to the softer plastic material's sound-absorbing properties. The similarity in bottom housing material ensures that the typing experience is consistent in terms of sound and feel between the two switches. Even though the top housing may contribute to variations in sound profiles, the shared nylon bottom housing maintains a certain level of uniformity in the overall typing experience.
Overall, the choice between the Gateron CM and the Outemu Purple switches may come down to personal preference regarding sound profiles and aesthetic considerations. The CM's nylon top housing provides a duller and rounder sound, while the Purple's polycarbonate top housing creates a clearer and resonant sound. Depending on whether RGB lighting effects are a priority for the user, the polycarbonate top housing of the Purple may be more appealing visually. However, both switches offer a consistent typing experience due to their shared nylon bottom housing, ensuring a deep and full sound profile regardless of the top housing material choice. Ultimately, the decision between these switches may hinge on individual preferences for sound and aesthetics.
Weight
When comparing the Gateron CM linear switch and the Outemu Purple tactile switch, the actuation force is lighter for the Purple at 50 grams compared to the CM's 55 grams. Both switches have an unknown bottom out force, but the CM is slightly heavier at 63.5 grams. The CM switch offers a medium-heavy typing experience, while the Purple switch provides a lighter actuation force for a smoother keystroke. For those who prefer a more substantial typing feel, the CM switch may be the better choice due to its heavier actuation force and bottom out force. However, for users who want a lighter touch and less finger fatigue during longer typing or gaming sessions, the Purple switch may be more suitable. Ultimately, the choice between the two switches depends on individual preferences for actuation and bottom out forces.
Travel distance
The Gateron CM linear switch has a travel distance of 3.6mm, making it shorter than the Outemu Purple tactile switch, which has a travel distance of 4mm. The CM switch falls into the category of shorter travel distances, which is favored by gamers for its faster response times. On the other hand, the Purple switch provides a more substantial depth during key presses, which some users may prefer for a more tactile experience. Ultimately, the choice between the two switches will depend on personal preference and the desired level of keypress feedback. Both switches offer unique characteristics that cater to different needs, so selecting one over the other will result in distinct typing experiences.

Typing experience
When it comes to sound, the Gateron CM linear switch stands out with its bassy, thocky, and low-pitched profile, creating a deep and rich auditory experience during key presses. On the other hand, the Outemu Purple tactile switch does not have any specific sound descriptors provided. This indicates that the sound profile of the Purple switch may not have distinct characteristics like the CM switch, potentially resulting in a more neutral or less pronounced sound. However, it's important to note that the overall sound of a switch can also be influenced by factors such as the keyboard's construction and keycaps used.
Moving on to the feel of the switches, the Gateron CM switch is described as buttery, polished, creamy, and frictionless, offering a smooth, fluid, and effortless typing experience. The switches are designed to provide a seamless and uniform sensation as you glide your fingers across the keys. In contrast, the Outemu Purple switch does not have any specific feel descriptors listed. This lack of information suggests that the tactile feel of the Purple switch may not have been highlighted compared to the CM switch. As a result, the typing experience on the Purple switch may be perceived as more standard or traditional without distinct attributes.
In conclusion, the Gateron CM linear switch excels in both sound and feel categories, providing a bouncy and bassy sound profile coupled with a buttery and frictionless typing experience. On the other hand, while the specific qualities of the Outemu Purple tactile switch remain unknown, it may offer a more neutral sound and tactile feel. If one desires a switch with similar characteristics to the Gateron CM, opting for the Outemu Purple switch may still yield comparable results, albeit with potentially less pronounced sound and feel qualities. Ultimately, the choice between the two switches will depend on personal preferences for sound, feel, and overall typing experience.
Conclusion
Therefore, in deciding between the Gateron CM linear switch and the Outemu Purple tactile switch, you should consider your preference for typing experience. If you value a smooth and bouncy typing journey with a deeper sound profile, the Gateron CM switch with its nylon housing, impeccable lube job, and dual-staged spring may be the better choice for you. On the other hand, if you prioritize a tactile feedback and a different sound experience, albeit without the specific details provided for the Outemu Purple switch, then the Purple tactile switch could be more suitable for your typing needs. Ultimately, your decision should be based on personal preferences and the specific typing experience you are looking to achieve with your mechanical keyboard switches.
