Bsun Guyu vs. Jerrzi Poseidon
An in-depth look at the Bsun Guyu and the Jerrzi Poseidon switches—which one is the best fit for you?
Overview
When comparing the BSUN Guyu linear switch to the Jerrzi Poseidon linear switch, it is evident that each offers unique characteristics that cater to different preferences. The Guyu stands out with its all-POM housings that enhance acoustics, creating a bright and crisp sound upon bottoming out, making typing sessions a smooth and resonant experience. On the other hand, the Poseidon does not have specific standout features mentioned but may appeal to those looking for a more straightforward and traditional linear switch. Both switches offer a smooth keystroke, but the Guyu is described as clacky, creamy, and snappy, while the Poseidon's characteristics are not specified. 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 Bsun Guyu and the Jerrzi Poseidon are both made of POM, which creates a pleasing and unique sound profile with deeper tones that are relatively more muted. This similarity in material results in a consistent sound experience for both switches. However, where they differ is in how the housing material is utilized in the top and bottom parts of the switch. The Guyu's POM top and bottom housings contribute to the overall sound profile, with the bottom housing affecting the bottom-out sound and feel, while the top housing influences the sound when a key is released.
While both switches feature POM housing materials that provide a similar sound profile, the design and construction of the Bsun Guyu and Jerrzi Poseidon differ in terms of how the housing material affects the overall typing experience. The split between the top and bottom housings allows for more control over specific aspects of the sound and feel of the switch. The Guyu's POM top housing impacts the sound when a key is released, while the POM bottom housing influences the bottom-out sound and feel. In comparison, the Poseidon's housing materials have a similar split effect, ensuring a consistent typing experience with nuanced differences in sound and feel.
Overall, the Bsun Guyu and the Jerrzi Poseidon showcase the versatility and impact of POM housing materials in mechanical switches. The unique sound profile characterized by deeper tones and muted qualities is a common feature in both switches, providing a satisfying typing experience for users. The strategic placement of the housing materials in the top and bottom parts of the switch allows for a more controlled and nuanced sound and feel, enhancing the overall typing experience. Whether it's the Guyu or the Poseidon, both switches offer a high-quality typing experience with POM housing materials playing a significant role in shaping the sound profile and tactile feedback.
Weight
When comparing the actuation force and bottom out force of the Bsun Guyu linear switch and Jerrzi Poseidon linear switch, it is clear that the Poseidon is lighter in terms of actuation force at 40 grams compared to the Guyu's 45 grams. However, the bottom out force of the Guyu is lighter at 50 grams, while the Poseidon's bottom out force is unknown. The actuation force of a switch is crucial as it determines the force required to trigger a keystroke, while bottom out force measures the force needed to press the key all the way down. Some users may prefer the lighter actuation force of the Poseidon for extended typing or gaming sessions, while others may prefer the heavier bottom out force of the Guyu for a more substantial typing experience. Ultimately, the choice between the two switches will depend on individual preferences for typing feel and force required for key presses.
Travel distance
The Bsun Guyu linear switch has a travel distance of 3.6 mm, while the Jerrzi Poseidon linear switch has a travel distance of 3.4 mm. Both switches fall within the range of shorter travel distances, making them popular choices for gamers looking for faster response times. The Guyu has a slightly longer travel distance than the Poseidon, which may provide a slightly more substantial feel when pressing down on the keys. However, the 0.2 mm difference in travel distance may not be significant enough to notice a major distinction between the two switches in terms of feel. Ultimately, both switches offer a relatively short travel distance compared to traditional options, catering to users who prefer a more responsive typing experience.

Typing experience
When it comes to sound, the BSUN Guyu linear switch stands out for its distinctive clacky nature, providing a sharp and snappy sound that resonates with a crisp brightness. The all-POM housing and long pole stem work together to create a unique acoustic experience, offering a satisfying typing rhythm that is both deep and clear. On the other hand, information on the Jerrzi Poseidon linear switch's sound quality is not available, so it is difficult to directly compare the two switches in this aspect. However, it is important to note that the sound of a switch can also be influenced by factors such as the keyboard board and keycaps used.
Moving on to the feel of the switches, the Guyu linear switch is praised for its creamy, frictionless, and polished attributes, providing a smooth and effortless typing experience that feels like gliding your fingers across the keys with ease. With a silky sensation and snappy responsiveness, the Guyu switch boasts a well-rounded tactile experience that enhances typing efficiency. Unfortunately, specific information regarding the feel of the Poseidon linear switch is not available, making it challenging to compare the two switches directly in terms of tactile feedback.
In conclusion, the BSUN Guyu linear switch excels in both sound and feel aspects, offering a unique auditory experience with its clacky sound profile and providing a smooth and effortless typing feel with its creamy, frictionless attributes. While information on the Jerrzi Poseidon linear switch is limited, based on the available data, it is clear that the Guyu switch provides a well-balanced blend of sound and feel qualities that contribute to a satisfying typing experience. If you are seeking a switch with similar characteristics to the Guyu, opting for a linear switch with POM housing, a long pole stem, and high-grade stem materials may result in a comparable typing experience.
Conclusion
To wrap up, when deciding between the Bsun Guyu linear switch and the Jerrzi Poseidon linear switch, you should consider your preference for auditory experience and feel. If you value a unique sound signature with deep acoustics and smooth keystrokes, the Guyu switch with its medium weight and high-grade UPE stem would be a great choice. On the other hand, if you prioritize a different aspect such as silent operation, the availability of Jerrzi Poseidon with its nonegram bottom out force might suit your needs better. Ultimately, your decision should be based on what sound and feel you prefer in your mechanical keyboard switches.
