Gateron CM vs. SP-Star Polaris Gray
An in-depth look at the Gateron CM and the SP-Star Polaris Gray switches—which one is the best fit for you?
Overview
When it comes to choosing a mechanical keyboard switch, two popular options to consider are the Gateron CM and the SP-Star Polaris Gray, both of which are linear switches. The Gateron CM switches offer a unique feature with their full nylon housing, breaking away from the conventional polycarbonate housings. This feature not only gives these switches a bold look but also contributes to a richer and deeper sound signature. Additionally, the impeccable factory lube job ensures an effortlessly smooth typing journey, creating a sensation of gliding gracefully with each keystroke. The CM switches are also known for their lengthened, dual-staged spring, providing a bouncy typing experience. On the other hand, the Polaris Gray switches excel at delivering a clean and clacky sound profile, perfect for those who prefer a bouncy typing experience. While both switches offer their own set of characteristics, let's dive in a bit deeper beyond these generalities so you can best decide on the switch that suits your preferences and needs.

Housing materials
The Gateron CM and the SP-Star Polaris Gray have contrasting housing materials. The CM features a nylon top housing, which provides a deeper and fuller sound profile. The relatively softer nylon absorbs more sound, resulting in a duller and rounder sound. On the other hand, the Polaris Gray utilizes a polycarbonate top housing, which creates a sharper, higher-pitched, and crisper sound. This is due to polycarbonate being a stiffer plastic, allowing for a more clear and resonant sound. Additionally, the Polaris Gray's top housing's translucency makes it ideal for RGB lighting.
Similarly, the two switches have contrasting bottom housings. The CM's nylon bottom housing elicits a deeper and fuller sound profile, thanks to the relatively softer nylon material that absorbs sound. In contrast, the Polaris Gray's polycarbonate bottom housing produces a sharper, higher-pitched, and crisper sound due to its stiffness. The translucent nature of the polycarbonate material also makes it more suitable for RGB lighting, enhancing the visual aesthetics of the switch.
It's worth noting that if a switch has different top and bottom housings, the qualities of each material will be split between the top and bottom of the switch. When pressing down on the switch, the bottom housing will have a greater impact on the bottom-out sound and feel. Conversely, the top housing will have a more significant influence on the sound produced when letting go of a key. Despite the differences in materials, both switches offer their unique sound profiles and visual appeal based on their housing materials.
Weight
When comparing the Gateron CM linear switch and the SP-Star Polaris Gray linear switch, it is notable that both switches have a medium-heavy bottom out force. However, there is a slight difference in their actuation force. The Gateron CM requires 55 grams of force for actuation, whereas the actuation force for the Polaris Gray is unavailable.
Considering weight as an important factor, those who prefer lighter switches may opt for the Gateron CM as it allows for longer typing sessions and is suitable for work or extended gaming periods. On the other hand, individuals who appreciate a stronger push and desire a more substantial typing experience may lean towards switches with heavier forces, such as the Polaris Gray with a bottom out force of 67 grams.
Although the actuation force for the Polaris Gray is unknown, it is reasonable to assume that it falls within a similar range as the Gateron CM due to both switches having a medium-heavy bottom out force. Therefore, users can expect similar results in terms of actuation force between the two switches. Overall, the choice between the two switches ultimately depends on individual preference for typing feel and the desired force required for keystrokes.
Travel distance
The Gateron CM linear switch and the SP-Star Polaris Gray linear switch have different travel distances. The CM has a travel distance of 3.6 mm, while the Polaris Gray has a travel distance of 4 mm. This means that the Polaris Gray has a slightly longer travel distance compared to the CM. A travel distance of 4 mm is considered more traditional, while a shorter travel distance of 3.6 mm is becoming increasingly popular, especially among gamers who prioritize faster response times. Choosing the switch with the shorter travel distance can provide a more responsive typing experience. However, some individuals may find shorter travel distances to be too abrupt. For those who prefer a deeper keypress, the switch with the longer travel distance may be the better choice. Ultimately, the decision will depend on personal preference and the desired typing experience.

Typing experience
In terms of sound, the Gateron CM switches are best known for their bassy, thocky, and low-pitched sound profile. These switches offer a deeper and richer sound during key presses, with a lower frequency range resembling the depth and richness associated with bass tones. Additionally, the sound they produce is characterized by a satisfying "thud" or "knock" when the key is pressed and released. On the other hand, the SP-Star Polaris Gray switches also have a low-pitched and thocky sound profile. Similar to the CM switches, they offer a more bass-heavy and mellow tone, producing a deep and rich sound during key presses.
When it comes to feel, the Gateron CM switches are described as buttery, polished, creamy, and frictionless. These switches provide a smooth and fluid keystroke experience, with reduced friction and smooth key travel. Typing on CM switches feels effortless and uniform, as if gliding gracefully with each keystroke. On the other hand, the SP-Star Polaris Gray switches are described as mild and polished, offering a gentle typing experience with a smooth and refined finish. These switches provide a sleek typing experience with reduced friction and smooth key travel.
In conclusion, both the Gateron CM and SP-Star Polaris Gray switches offer similar qualities in terms of sound and feel. They both have a low-pitched and thocky sound profile, producing a deep and rich sound during key presses. In terms of feel, they both provide a smooth and refined typing experience with reduced friction and smooth key travel. While the CM switches have additional descriptors like buttery, creamy, and frictionless, the Polaris Gray switches are described as mild. It's important to note that the sound and feel of switches may vary depending on other factors such as the keyboard board and keycaps used.
