Jerrzi Poseidon vs. SP-Star Duck
An in-depth look at the Jerrzi Poseidon and the SP-Star Duck switches—which one is the best fit for you?
Overview
When considering mechanical keyboard switches, two popular options that often come up are the Jerrzi Poseidon, a linear switch, and the SP-Star Duck, a tactile switch. The Poseidon is best known for its smooth linear feel, making it ideal for fast typists and gamers. On the other hand, the Duck switch offers a more subtle tactile typing experience, providing gentle tactility and a clean sound profile. The Poseidon is categorized as a linear switch, while the Duck is classified as a neutral, mild switch with a buttery, polished feel. Each switch has its unique characteristics and appeal, ultimately catering to different preferences and typing styles. However, let's delve a bit deeper beyond generalities so you can best decide on the right switch for you.

Housing materials
The Jerrzi Poseidon and SP-Star Duck both offer unique housing materials that contribute to the overall sound profile of the switches. The Poseidon utilizes POM for both its top and bottom housings, creating a deeper and more muted sound. In contrast, the Duck features polycarbonate for both top and bottom housings, resulting in a sharper, higher-pitched, and crisper sound. While both materials offer distinct sonic characteristics, the Poseidon's POM creates a more subdued sound compared to the Duck's polycarbonate, which produces a more vibrant and resonant tone.
The choice between POM and polycarbonate housing materials also impacts the aesthetic features of the switches. With polycarbonate's translucency, the Duck offers a visually appealing option for users who prioritize RGB lighting in their setups. On the other hand, the Poseidon's POM housing may not provide the same level of visual flair but focuses on delivering a unique and pleasing sound experience. Whether you prefer a switch that catches the eye with its clear housing or prioritizes a deeper, more subtle sound profile, both the Poseidon and Duck offer distinct options for mechanical keyboard enthusiasts.
Ultimately, the differences between the housing materials of the Jerrzi Poseidon and SP-Star Duck result in contrasting sound profiles that cater to different preferences. While the Poseidon's POM housing creates a more muted and deep sound, the Duck's polycarbonate housing offers a sharper and crisper tone. The split between top and bottom housings means that each material's unique qualities are felt differently during key presses, with the bottom housing impacting the bottom-out sound and feel, while the top housing influences the sound when a key is released. Whether you prioritize sound quality or visual aesthetics, both switches provide distinct options for mechanical keyboard enthusiasts to choose from.
Weight
The Jerrzi Poseidon linear switch has a lighter actuation force of 40 grams compared to the SP-Star Duck tactile switch, which has an unknown actuation force. However, the Duck has a heavier bottom out force of 58 grams, while the Poseidon's bottom out force is unavailable. This means that the Duck provides a more substantial typing experience with a heavier push feel when compared to the Poseidon. The differences in weight between these switches cater to different preferences; those who prefer a lighter touch may lean towards the Poseidon for longer typing sessions, while those who enjoy a more pronounced keystroke might opt for the Duck. Ultimately, the choice between these two switches will depend on whether one values a lighter actuation force or a heavier bottom out force for their typing experience.
Travel distance
When comparing the travel distance of the Jerrzi Poseidon linear switch and the SP-Star Duck tactile switch, it is clear that the Poseidon has a shorter travel distance at 3.4 mm compared to the Duck's 4 mm. The Poseidon's shorter travel distance is ideal for those seeking faster response times, such as gamers, due to less distance needed to actuate the switch. On the other hand, the Duck's longer travel distance may provide a more satisfying and deliberate key press for those who prefer a deeper feel. Both switches offer different experiences based on their travel distances, so the choice between the two ultimately depends on personal preference and typing style. Ultimately, the Poseidon's shorter travel distance may result in quicker key presses, while the Duck's longer travel distance may offer a more substantial feel.

On the other hand, the SP-Star Duck tactile switch is described as having a neutral sound profile. This means it has a moderate sound level, suitable for various settings and users. However, it's important to note that the sound of a switch can also be influenced by other factors such as the keyboard case and keycaps used.
When it comes to feel, the Jerrzi Poseidon linear switch does not have specific descriptors available. In contrast, the SP-Star Duck tactile switch is known for providing a mild and buttery typing experience. This means the tactile feedback is gentle and smooth, offering a comfortable typing sensation. Additionally, the switch is described as polished, indicating a refined finish that reduces friction and ensures seamless key travel.
Overall, if you prefer a quieter typing experience, the Jerrzi Poseidon linear switch would be the better choice. However, if you're looking for a gentle and smooth tactile feedback, the SP-Star Duck tactile switch is the way to go. Both switches offer their own unique qualities that cater to different preferences, so selecting the one that aligns with your typing style and environment is key to maximizing your mechanical keyboard experience.
Conclusion
In closing, when deciding between the Jerrzi Poseidon linear switch and the SP-Star Duck tactile switch, consider your preference for tactile feedback and sound profile. If you enjoy a more subtle tactile typing experience with a clean and crispy sound profile, the Duck switches would be a great choice for you. On the other hand, if you prefer a switch with no bottom out force and a different sound profile, the Poseidon switches may be more suitable for your needs. Ultimately, your decision should be based on your personal typing preferences and the overall typing experience you are looking for in a mechanical keyboard switch. Choose wisely and happy typing!
