Akko Penguin vs. HMX SU
An in-depth look at the Akko Penguin and the HMX SU switches—which one is the best fit for you?
Overview
When choosing the ideal mechanical keyboard switch, preferences often boil down to tactile versus linear designs, with the Akko Penguin and HMX SU representing two distinct options. The Akko Penguin switches stand out in the realm of tactile switches for their soft yet pronounced feel, boasting a rounded tactile bump that delivers satisfying feedback while ensuring a quiet operation — a perfect fit for office environments where noise reduction is crucial. Conversely, the HMX SU switches, characterized by their linear design, provide a smooth and uninterrupted keypress experience, appealing to those who favor a minimalist sound profile that avoids the distractions of clicky feedback. While the Penguin's medium weight strikes a balance ideal for extended typing sessions, the SU’s PA12 housing and T5 stem promise a deeper audio experience without the tactile interruptions. These differences highlight the diverse functionalities of each switch, making them suitable for varying user needs and environments. 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 Akko Penguin and the HMX SU switches demonstrate striking similarities, particularly in their use of nylon for both the top and bottom housings. Nylon is celebrated for its sound-dampening characteristics, and both switches utilize this material to elicit a deeper and fuller sound profile during typing. This common choice among both switches results in a typing experience characterized by a duller and more rounded sound, as the softer plastic absorbs more sound compared to harder alternatives. Consequently, users of both the Penguin and the HMX SU can anticipate similar auditory feedback, enhancing the enjoyment of typing with either switch.
Furthermore, the uniformity in housing materials means that the sonic qualities will be harmoniously aligned across both switches. The nylon makes a significant contribution both to tactile feedback and auditory result, as the bottom housing’s impact is more pronounced when the switch is bottomed out, while the top housing affects the sound produced upon release. Since both the Penguin and HMX SU utilize this same nylon configuration, users will likely perceive comparable tactile impressions regardless of which switch they choose. The dual use of nylon in both top and bottom housings effectively maintains a consistent performance, emphasizing the full sound profile that each switch offers.
Despite the identical use of nylon, variations in design and engineering might still affect the overall feel and response of the switches. While both switches are built from the same material, the specific construction and internal components might yield slight differences in typing experience—such as actuation force and tactile feedback. Hence, while the housing materials align closely, it is essential for users to explore both products to discern any nuances that might cater better to their preferences. Ultimately, whether one opts for the Akko Penguin or the HMX SU, the similarity in housing materials will foster a comparable auditory experience, even if the subtleties in feel still warrant further exploration.
Weight
When comparing the Akko Penguin tactile switch and the HMX SU linear switch, a few notable differences in their actuation and bottom out forces emerge. The Akko Penguin has an actuation force of 43 grams and a bottom out force of 60 grams, which categorizes it as a medium-weight switch. In contrast, the HMX SU linear switch has a slightly higher actuation force of 45 grams but a notably lighter bottom out force of 50 grams. This makes the HMX SU feel lighter overall, particularly when considering that it bottoms out at a lower force. For users who prefer lighter switches for prolonged typing or gaming sessions, the HMX SU linear switch would be the preferred choice due to its ease of keypress, despite its slightly heavier actuation force. Conversely, those who appreciate a more substantial typing experience might gravitate towards the Penguin switch, which offers a firmer bottoming out sensation. Overall, while both switches provide a unique typing experience, the Penguin offers a heavier feel compared to the lighter, more accessible touch of the HMX SU.
Travel distance
When comparing the travel distance of the Akko Penguin tactile switch and the HMX SU linear switch, notable differences emerge. The Akko Penguin has a travel distance of 3.3 mm, while the HMX SU features a slightly longer travel distance of 3.6 mm. This means that the Penguin shortens the distance you need to press compared to the SU, which may be advantageous for gamers seeking quicker response times. However, some users might find the shorter distance of the Penguin to feel too abrupt, preferring the more substantial 3.6 mm travel of the HMX SU for a deeper, more deliberate typing experience. Therefore, if you prioritize rapid actuation, the Akko Penguin would be the better choice, but for those who enjoy a more traditional feel, the HMX SU offers a longer travel distance.

Typing experience
When it comes to sound, the Akko Penguin tactile switches stand out with their muted and neutral characteristics. They are designed to minimize noise, making them suitable for office environments or shared spaces where quiet operation is essential. The muted actuation produces a softer and subtler sound compared to traditional mechanical switches, while the neutral aspect ensures that the sound profile is neither too intrusive nor overly silent, striking a good balance for all types of users. In contrast, the HMX SU linear switch lacks specific sound descriptions, leaving its auditory properties open to interpretation, but sound can vary significantly based on the keyboard build and keycap material used, suggesting that it might deliver a deeper sound profile given its construction.
In terms of feel, the Akko Penguin switches offer a polished and mild typing experience. The polished finish allows for smoothly engaging keystrokes with reduced friction, which enhances the overall tactile feedback while typing. The mild characteristics suggest that users can enjoy a gentle yet secure sensation during use, making it approachable for both beginners and seasoned typists. The Penguin switches are also described as feathery and subtle, indicating that they require minimal exertion and provide a light resistance that is easy on the fingers for extended typing sessions. Meanwhile, no specific feel qualities are provided for the HMX SU linear switch, leaving its tactile engagement undisclosed.
In summary, the Akko Penguin tactile switches deliver a well-rounded, muted sound profile and a smooth, gentle feel that is conducive to long typing sessions, making them ideal for both work and gaming environments. Their subtle, polished characteristics cater to users looking for comfort without sacrificing feedback. The lack of detailed auditory and tactile information for the HMX SU linear switch raises uncertainty about its overall qualities, which leaves potential users with the need for further experimentation or feedback from the community to gauge its performance in comparison.
Conclusion
To conclude, choosing between the Akko Penguin tactile switch and the HMX SU linear switch ultimately depends on your specific preferences and the typing environment you are in. If you find yourself in a shared office space or value a quieter typing experience, the Penguin switch is your best option. Its muted yet tactile feedback helps you maintain productivity without disturbing coworkers, while the medium actuation force offers an excellent balance that avoids finger fatigue during extended typing sessions. On the other hand, if you prefer a lighter touch and seek a smoother, more linear typing experience for gaming or casual typing, the HMX SU switch might be more appealing. With its light bottom-out force and a relatively deep sound profile, it caters well to those who appreciate a smooth keypress without the bump of a tactile switch. Thus, consider your typing habits, environment, and personal taste to determine which switch will best enhance your mechanical keyboard experience.
