Bsun Guyu vs. Outemu Lime
An in-depth look at the Bsun Guyu and the Outemu Lime switches—which one is the best fit for you?
Overview
When comparing the Bsun Guyu linear switch to the Outemu Lime tactile switch, we see two distinct options for mechanical keyboard enthusiasts. The Guyu switch is praised for its auditory experience, with all-POM housings enhancing acoustics and a long pole stem creating a bright, crisp sound upon bottoming out. It offers a medium weight that complements smooth keystrokes, resulting in effortless typing sessions with resonant feedback. On the other hand, the Lime switch stands out for its lightweight design, subtle tactility, and silencing properties, making it ideal for those who prefer a feathery typing experience with just a touch of feedback. Both switches showcase unique characteristics that cater to different preferences, but as with any mechanical keyboard switch choice, it ultimately comes down to personal preference. 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 Outemu Lime both utilize different housing materials in their switches, with the Guyu featuring POM housings and the Lime featuring nylon housings. Both of these materials are known for creating a deeper and fuller sound profile, but they achieve this in slightly different ways. The POM housings of the Guyu are described as creating a more muted sound, while the nylon housings of the Lime are said to create a duller and rounder sound. This difference in sound profile could lead to a preference for one over the other based on personal taste in typing experience.
In terms of construction, the Guyu has POM top and bottom housings, while the Lime has nylon top and bottom housings. This means that the qualities of each housing material are evenly distributed throughout the switch. The bottom housing of a switch typically has more impact on the bottom-out sound and feel, while the top housing affects the sound when releasing a key. As such, users may notice a variance in sound and feel depending on which housing material is used in the top versus the bottom of the switch.
Overall, both the Bsun Guyu and Outemu Lime offer unique typing experiences due to their choice of housing materials. While both switches create a deep and full sound profile, the POM housings of the Guyu produce a more muted sound compared to the duller and rounder sound of the nylon housings in the Lime. Ultimately, the decision between the two switches may come down to individual preferences in typing feel and sound, as well as the specific characteristics that each housing material brings to the overall experience.
Weight
The Bsun Guyu linear switch and the Outemu Lime tactile switch both offer relatively light actuation and bottom out forces, with the Guyu having a slightly heavier actuation force of 45 grams compared to the Lime's 35 grams. However, when it comes to bottom out force, the Guyu requires 50 grams compared to the Lime's 45 grams. This means that the Guyu switch provides a slightly heavier and more substantial typing experience compared to the Lime switch. Those who prefer a lighter typing feel may opt for the Lime switch, while those who enjoy a bit more resistance might lean towards the Guyu switch. Ultimately, both switches offer a comfortable typing experience, with the choice between them coming down to personal preference for actuation and bottom out forces.
Travel distance
The Bsun Guyu linear switch has a travel distance of 3.6 mm, while the Outemu Lime tactile switch has a slightly shorter travel distance of 3.3 mm. Both switches fall on the shorter end of the spectrum compared to the more traditional 4.0 mm travel distance. Gamers may prefer the Outemu Lime for its slightly faster response time due to the shorter travel distance, while those who enjoy a more substantial keypress may lean towards the Bsun Guyu. Ultimately, the choice between the two switches comes down to personal preference in terms of keypress feel and response time.

In contrast, the Outemu Lime tactile switch provides a more neutral and muted sound profile, catering to those who prefer a quieter typing experience. Both switches offer distinct sound characteristics that can enhance the overall typing atmosphere, although the Guyu leans towards a sharper tone while the Lime focuses on a softer and more subtle auditory output.
In terms of feel, the Bsun Guyu switch provides a creamy, frictionless, and polished typing experience, allowing for smooth and effortless keystrokes with minimal resistance. On the other hand, the Outemu Lime switch offers a mild and feathery feel, making it comfortable for extended typing sessions with its light actuation force. Both switches aim to provide a pleasant typing sensation, with the Guyu emphasizing a polished and snappy touch while the Lime focuses on a gentle and approachable tactility.
Considering the subjective qualities of sound and feel, the Bsun Guyu linear switch and the Outemu Lime tactile switch offer contrasting yet appealing typing experiences. While the Guyu excels in delivering a clacky and creamy typing feel with resonant feedback, the Lime provides a neutral and feathery touch that is suitable for various preferences. Ultimately, choosing between these switches will depend on individual preferences for sound and feel, but rest assured, both options promise a satisfying typing experience with their respective unique qualities.
Conclusion
In closing, when deciding between the Bsun Guyu linear switch and the Outemu Lime tactile switch, you should consider the unique characteristics of each. If you are looking for a keyboard switch that offers a distinctive auditory experience with smooth keystrokes and resonant feedback, then the Bsun Guyu linear switch would be a great choice for you. On the other hand, if you prefer a lightweight switch with a touch of tactility and silent operation, the Outemu Lime tactile switch may be more suitable for your needs. Ultimately, your decision should be based on your personal preferences for sound, feel, and typing experience. Choose the switch that aligns best with your typing style and preferences to enhance your overall typing experience.
