Bsun Guyu vs. Kailh Plum

Overview

When considering mechanical keyboard switches, two popular options that often come up are the Bsun Guyu, a linear switch, and the Kailh Plum, a tactile switch. The Bsun Guyu is renowned for its unique auditory experience, with all-POM housings that deepen the acoustics and a bright, crisp bottom-out sound created by a long pole stem. The medium weight and super-smooth keystrokes provided by the high-grade UPE stem make typing effortless and enjoyable, offering a distinct sound signature that combines depth and clarity. On the other hand, the Kailh Plum stands out for its hefty feel without a pronounced tactile bump, setting it apart from other tactile switches. Its neutral and enjoyable sound profile adds to the typing experience. While the Guyu is described as 'Clacky', 'Creamy', 'Frictionless', 'Polished', 'Silky', 'Snappy', the Plum is categorized as 'Neutral', 'Mild', 'Stepped'. Depending on your preferences for sound, feel, and typing style, either of these switches could be a great choice. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials

The Bsun Guyu and the Kailh Plum both use different materials for their top and bottom housings, with the Guyu using POM for both top and bottom housings while the Plum uses polycarbonate for the top housing and nylon for the bottom housing. The POM top housing of the Guyu creates a deeper and more muted sound profile, whereas the polycarbonate top housing of the Plum produces a sharper and crisper sound. On the other hand, the nylon bottom housing of the Plum elicits a deeper and fuller sound, while the POM bottom housing of the Guyu also contributes to a deeper sound profile. Despite the differences in materials used, both switches aim to create pleasing and unique sound profiles for users.

One key distinction between the two switches lies in the impact of the housing material on the sound and feel of typing. The bottom housing material, whether it be POM or nylon, plays a significant role in the bottom-out sound and feel of the switch when pressed down. The softer nylon material in the Plum's bottom housing absorbs more sound, resulting in a duller and rounder sound profile. Conversely, the top housing material, whether it be POM or polycarbonate, influences the sound produced when a key is released. The stiffer polycarbonate material in the Plum's top housing leads to a clearer and more resonant sound when keys are let go, while the POM top housing of the Guyu creates a more muted sound profile upon key release.

Overall, both the Bsun Guyu and the Kailh Plum offer users distinct sound profiles based on the materials used in their housing. The use of POM in the Guyu results in a unique and pleasing sound profile that leans towards the deeper and more muted side, while the combination of polycarbonate and nylon in the Plum creates a sharper and crisper sound. Whether you prefer a fuller, deeper sound or a more resonant and clear sound, both switches provide options for different preferences in typing sound and feel. Despite the differences in material composition, users can expect similar results in terms of unique and pleasing sound profiles from both the Bsun Guyu and the Kailh Plum.

Weight

The Bsun Guyu linear switch has a lighter actuation force of 45 grams and a slightly heavier bottom out force of 50 grams, providing a relatively light typing experience overall. In contrast, the Kailh Plum tactile switch has an unknown actuation force but a significantly heavier bottom out force of 70 grams, giving it a more substantial and tactile typing feel. Those who prefer a lighter touch may opt for the Guyu switch for longer typing sessions or gaming, while those who enjoy a stronger push feel may prefer the Plum switch for a more pronounced typing experience. Ultimately, the choice between the two switches will depend on the individual's preference for actuation and bottom out forces.

Travel distance

Both the Bsun Guyu linear switch and the Kailh Plum tactile switch have the same travel distance of 3.6mm, making them equally ideal for gamers and typists looking for a responsive and comfortable typing experience. With their identical travel distances, users can expect similar results in terms of keypress feedback and overall typing feel. The consistent travel distance of both switches ensures a familiar and reliable typing experience, whether for gaming or everyday use.

Typing experience

When it comes to sound, the Bsun Guyu linear switch offers a clacky experience, producing a sharp and snappy sound that is bright, crisp, and percussive. This is a result of the all-POM housing and long pole stem creating a unique acoustics profile. On the other hand, the Kailh Plum tactile switch has a more neutral sound profile, offering a moderate sound that is enjoyable without being too intense. The choice of sound between the two switches ultimately comes down to personal preference and the overall setup of your keyboard.

In terms of feel, the Bsun Guyu linear switch is renowned for its creamy, frictionless, polished, silky, and snappy typing experience. This smooth and effortless glide is made possible by the high-grade UPE stem and carefully balanced weight of the switch. On the other hand, the Kailh Plum tactile switch offers a mild and stepped typing experience, providing a gentle and approachable feel with a two-stage tactile bump. Ultimately, the choice between the two switches will depend on whether you prefer a more buttery smooth typing experience or a mild, stepped tactility in your keys.

Overall, the Bsun Guyu linear switch and the Kailh Plum tactile switch offer unique and distinct qualities in terms of sound and feel. While the Guyu provides a clacky sound and a smooth, snappy typing experience, the Plum offers a neutral sound and a mild, stepped tactility. Both switches have their own strengths and it ultimately comes down to personal preference and the specific typing experience you are looking for. Depending on whether you prefer a sharper sound and a buttery smooth feel or a neutral sound and a mild tactility, you can achieve satisfying results with either switch.

Conclusion

To sum up, when considering whether to choose the BSUN Guyu linear switch or the Kailh Plum tactile switch, it ultimately boils down to your personal preferences in sound and feel. If you are looking for a unique auditory experience with a brighter, crisper bottom-out sound and smooth keystrokes, the Guyu switch may be the right choice for you. On the other hand, if you prefer a switch with a moderate actuation force requirement and a neutral sound profile, the Plum switch could be more suitable. Both switches have their own distinct characteristics that cater to different typing preferences, so it's important to consider what qualities matter most to you when making your decision. Ultimately, the choice between the Guyu and Plum switches will depend on what features you prioritize in your mechanical keyboard experience.
