Bsun Guyu vs. Gateron Lunar Probe
An in-depth look at the Bsun Guyu and the Gateron Lunar Probe switches—which one is the best fit for you?
Overview
The Bsun Guyu and Gateron Lunar Probe are two popular linear mechanical keyboard switches offering unique features to enhance your typing experience. The Bsun Guyu stands out for its all-POM housing and long pole stem, delivering a bright and crisp bottom-out sound. With a medium weight and super-smooth keystrokes thanks to the high-grade UPE stem, typing on the Guyu switch becomes effortless and resonant. On the other hand, the Gateron Lunar Probe features a dual rail mechanism for stable keypresses and a pre-lubed linear sensation for smooth typing. While the Guyu is described as clacky, creamy, and polished, the Lunar Probe provides a silent yet satisfying typing experience. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The differences between the housing materials of the Bsun Guyu and the Gateron Lunar Probe are quite distinct. The Guyu features a POM top housing, known for creating a deeper and more muted sound profile. On the other hand, the Lunar Probe showcases a polycarbonate top housing, which produces a sharper, higher-pitched, and crisper sound. This contrast in sound profiles can greatly impact the overall typing experience for users of these switches. Additionally, the translucency of polycarbonate in the Lunar Probe's top housing allows for RGB lighting to shine through, adding a visual element to the typing experience.
Moving on to the bottom housing materials, the Guyu utilizes POM, which again provides a deep and muted sound profile. In contrast, the Lunar Probe features a nylon bottom housing, offering a deeper and fuller sound when typing. Nylon's softer plastic absorbs more sound, resulting in a duller and rounder sound compared to the POM material. This difference in bottom housing materials can significantly affect the overall typing feel and sound of the switches.
It is important to note that the impact of housing materials on the sound and feel of a switch is divided between the top and bottom housings. The bottom housing material plays a larger role in the bottom-out sound and feel when the key is pressed, while the top housing material has more of an impact on the sound when the key is released. Despite the differences in housing materials between the Bsun Guyu and the Gateron Lunar Probe, both switches offer unique sound profiles that cater to diverse preferences among keyboard enthusiasts.
Weight
The actuation force and bottom out force of the Bsun Guyu linear switch and the Gateron Lunar Probe linear switch are both the same, with an actuation force of 45 grams and a bottom out force of 50 grams. This means that users can expect similar results in terms of the force required to trigger a keystroke and the maximum force needed to press a key all the way down. Both switches are considered lightweight, which can be advantageous for prolonged typing or gaming sessions. Some users may prefer a lighter actuation force for extended use, while others may prefer a heavier bottom out force for a more substantial typing experience. Ultimately, the choice between the Guyu and Lunar Probe switches will come down to personal preference in terms of force sensitivity.
Travel distance
The Bsun Guyu linear switch and the Gateron Lunar Probe linear switch both have the same travel distance of 3.6 mm. This means that when pressing down on a key with either switch, you will experience the same amount of travel distance before the key registers. Both switches offer a consistent typing experience in terms of the distance the switch travels from the top to the bottom. However, if one was to look for the shorter one, the Bsun Guyu and the Gateron Lunar Probe linear switches are of the same length.

In terms of feel, the Bsun Guyu switch provides a creamy and polished typing experience, ensuring smooth and effortless keystrokes with a silky sensation. The switch's medium weight and high-grade UPE stem contribute to a frictionless and snappy typing feel, enhancing the overall responsiveness during typing sessions. In contrast, details about the Gateron Lunar Probe switch's feel are unknown, but its incredibly smooth and pre-lubed linear sensation suggests a comfortable and fluid typing experience. Both switches promise a pleasant feel, but the Guyu switch may offer a more refined and polished touch.
Overall, when looking at the subjective qualities of the Bsun Guyu linear switch and the Gateron Lunar Probe linear switch, it is evident that they cater to different preferences in sound and feel. The Guyu switch stands out for its clacky and lively sound signature, as well as its creamy and polished typing feel. On the other hand, the Lunar Probe switch offers a smoother and quieter typing experience, perfect for those who prefer a more subtle sound profile. Ultimately, depending on your preference for sound and feel, both switches offer a high-quality typing experience that is sure to enhance your overall keyboarding journey.
