Jerrzi Poseidon vs. Bsun Tomcat (Heavy)

An in-depth look at the Jerrzi Poseidon and the Bsun Tomcat (Heavy) switches—which one is the best fit for you?

Overview

When it comes to selecting the ideal mechanical keyboard switch for your typing or gaming experience, the Jerrzi Poseidon and Bsun Tomcat (Heavy) are two compelling linear options that cater to different preferences. The Jerrzi Poseidon presents a straightforward approach, focusing on a consistent keystroke feel that is perfect for those who appreciate a smooth and unimpeded typing experience without any tactile bumps or audible clicks. In contrast, the Bsun Tomcat (Heavy) is celebrated for its unique Ly stems, which contribute to a notably smooth typing experience, complemented by a resonant sound profile that adds a distinctive auditory quality to each keystroke. While both switches favor linear mechanics, the Poseidon may appeal to users seeking simplicity and reliability, whereas the Tomcat (Heavy) caters to those who enjoy a bit more character in their key presses. However, let's dive in a bit deeper beyond generalities so you can best decide on the switch that suits your needs.

Housing materials

When comparing the housing materials of the Jerrzi Poseidon and the Bsun Tomcat (Heavy), a marked distinction emerges between their top housings. The Poseidon utilizes POM (Polyoxymethylene) for its top housing, which is celebrated for creating a sound profile that is deeper and more muted, contributing to a unique auditory experience. In contrast, the Tomcat (Heavy) features a polycarbonate top housing, known for producing a sharper, higher-pitched, and crisper sound. The stiffer nature of polycarbonate allows for a more resonant sound, which enhances clarity, making this material especially well-suited for setups incorporating RGB lighting. While both materials have their merits, the resulting sound profiles diverge significantly, with the Poseidon emphasizing warmth and depth, while the Tomcat (Heavy) brings forth brightness and resonance.

When we turn our attention to the bottom housings, the differences continue. The Poseidon employs a POM bottom housing, echoing the characteristics of its top housing by providing a pleasant sound that remains relatively muted and deep. This consistency between the top and bottom ensures that the overall acoustic experience is harmonious, producing a unified sound signature. On the other hand, the Tomcat (Heavy) features a nylon bottom housing, which historically offers a fuller, deeper sound profile. The softer nature of nylon absorbs sound more effectively, leading to a duller and rounder acoustic quality. Consequently, the Tomcat (Heavy) creates a sound that is impactful during key presses while also offering a deeper felt response overall.

In essence, both switches demonstrate how the interaction of top and bottom housings influences functionality and sound. The Jerrzi Poseidon, with its uniform use of POM, achieves a cohesive sound profile that emphasizes a deeper tonality in both key press and release. Conversely, the Bsun Tomcat (Heavy) benefits from its combination of polycarbonate and nylon, producing a unique split in sound characteristics—clear and bright during actuation and deeper in sound upon bottoming out. Thus, while the Poseidon may deliver a more muted acoustic signature overall, the Tomcat (Heavy) leverages the contrasting qualities of its materials to yield an engaging complexity in typist experience.

Weight

The Jerrzi Poseidon linear switch and the Bsun Tomcat (Heavy) linear switch exhibit distinct differences in their actuation and bottom out forces. The Poseidon features a lighter actuation force of 40 grams, making it a preferable choice for users who favor a lightweight feel for prolonged typing or gaming sessions. In contrast, the Tomcat (Heavy) has a heavier actuation force of 55 grams, catering to those who appreciate a stronger push for a more substantial typing experience. However, while the actuation force of the Poseidon is known, its bottom out force remains unavailable. The Tomcat, on the other hand, has a defined bottom out force of 64 grams, which is classified as medium-heavy, further enhancing its tactile feedback. Thus, for users prioritizing lighter switches, the Poseidon is the better option, whereas those seeking a more robust typing experience with higher resistance should lean towards the Tomcat (Heavy).

Travel distance

When comparing the travel distances of the Jerrzi Poseidon linear switch and the Bsun Tomcat (Heavy) linear switch, it is clear that the Poseidon has a shorter travel distance of 3.4 mm, while the Tomcat (Heavy) features a longer travel distance of 3.6 mm. This distinction highlights the Poseidon as the more responsive choice, favored by gamers who appreciate quicker actuation for enhanced performance. In contrast, the Tomcat (Heavy), with its more substantial 3.6 mm travel distance, may appeal to those who prefer a deeper feel when typing or gaming, offering a more traditional tactile experience. Thus, choosing between these two options largely depends on whether one prioritizes responsiveness or depth in their keystrokes.

Price comparison

Typing experience

The Jerrzi Poseidon linear switch does not have a notable sound profile, which may contribute to a quieter typing experience, making it a good choice for those who value discretion in their mechanical keyboards. In contrast, the Bsun Tomcat (Heavy) linear switch features a resonant sound characteristic, which adds a unique auditory element that could enhance the typing experience for users who appreciate a bit of feedback without being overly loud. It's important to remember that the overall sound a switch produces can also be influenced by factors like the choice of keyboard, housing materials, and keycap design, so while the Tomcat has a more distinct sound, the Poseidon’s muted quality can be ideal for specific environments.

When it comes to feel, the Jerrzi Poseidon lacks a defined description, leaving its tactile response somewhat ambiguous. On the other hand, the Bsun Tomcat (Heavy) switch is known for its Ly stems, which provide a super smooth typing experience. This suggests that users of the Tomcat will enjoy a seamless keystroke that can enhance typing efficiency and comfort, especially over long durations. If the Poseidon switch does not offer a comparable smoothness, users might have varying experiences with drag or resistance, impacting their overall enjoyment.

In conclusion, while the Jerrzi Poseidon linear switch may serve well in a quieter typing environment, the Bsun Tomcat (Heavy) linear switch stands out for its smooth keystrokes and resonant sound profile. For those looking for a linear switch, the Tomcat promises an engaging tactile experience, whereas the Poseidon might be better suited for users who prioritize a low-noise solution. Ultimately, both switches cater to different preferences, allowing users to select a switch that aligns with their specific needs and typing styles.

Conclusion

To conclude, the choice between the Jerrzi Poseidon and the Bsun Tomcat (Heavy) linear switches hinges on your personal typing style and preferences. If you lean towards a lighter touch and prefer a more effortless keystroke, the Poseidon might be the better option for you. This switch is tailored for those who enjoy a smooth, gentle typing experience without the resistance found in heavier switches. On the other hand, if you prefer a firmer feedback and a more deliberate typing experience, the Tomcat (Heavy) switch would suit you well. With a bottom-out force of 64 grams, it caters to users who appreciate the tactile assurance that comes from a medium-heavy touch, making it excellent for both typing and gaming scenarios. Coupled with its smooth Ly stems, the Tomcat offers a resonant sound profile that many find satisfying. Ultimately, your decision should align with your comfort and typing preference; select the Poseidon for a light, airy feel, or the Tomcat (Heavy) for robust feedback and a premium sound experience.
