Gateron Lunar Probe vs. Outemu Milk Blue

An in-depth look at the Gateron Lunar Probe and the Outemu Milk Blue switches—which one is the best fit for you?

Overview

When it comes to comparing the Gateron Lunar Probe and the Outemu Milk Blue mechanical keyboard switches, there are key differences that set them apart. The Lunar Probe, a linear switch, is renowned for its innovative dual rail mechanism that ensures reliable and consistent keypresses. With a smooth, pre-lubed linear sensation and a subtle sound signature, it offers a comfortable typing experience. On the other hand, the Milk Blue is a clicky switch that provides a satisfying tactile feedback with each keypress. While the Lunar Probe excels in offering a smooth and stable typing experience, the Milk Blue stands out for its clicky feedback. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials

The Gateron Lunar Probe and the Outemu Milk Blue both feature polycarbonate top housings, which create a sharper, higher-pitched, and crisper sound profile due to the material's stiffness. This results in a more clear and resonant sound when typing, making them ideal for users looking for a distinctive sound experience. In addition, the translucent nature of polycarbonate allows for the integration of RGB lighting, adding a visual element to the typing experience. As a result, both switches offer similar qualities in terms of sound profile and aesthetics, making them popular choices among mechanical keyboard enthusiasts.

On the other hand, the Lunar Probe utilizes a nylon bottom housing, while the Milk Blue also features a nylon bottom housing. Nylon is known for producing a deeper and fuller sound profile compared to other plastics, as it absorbs more sound and creates a duller and rounder sound. This material choice enhances the typing experience by providing a unique sound profile that may appeal to users seeking a more tactile and immersive typing experience. By incorporating nylon in the bottom housing, both switches offer a balance of impact and sound when pressing down on the keys, contributing to a satisfying typing feel overall.

Overall, while both the Gateron Lunar Probe and the Outemu Milk Blue share similar qualities in their polycarbonate top housings, they differ slightly in their bottom housing materials. The split in housing materials allows each switch to offer a unique typing experience, with the bottom housing influencing the bottom-out sound and feel, while the top housing impacts the sound when releasing a key. This distinction adds complexity to the typing experience and gives users the opportunity to choose a switch based on their preferred sound profile and tactile feedback.

Weight

The Gateron Lunar Probe linear switch has a lighter actuation force of 45 grams compared to the Outemu Milk Blue clicky switch which has an actuation force of 50 grams. However, the bottom out force of the Lunar Probe is also lighter at 50 grams, while the bottom out force of the Milk Blue is unknown. For those who prefer a lighter typing experience, the Lunar Probe may be the better choice, allowing for longer typing sessions without fatigue. On the other hand, the Milk Blue may be preferred by those who enjoy a more substantial typing feel with a slightly heavier actuation force. Ultimately, the choice between the two switches will depend on individual preference for actuation and bottom out forces.

Travel distance

The Gateron Lunar Probe linear switch has a travel distance of 3.6mm, while the Outemu Milk Blue clicky switch has a travel distance of 4mm. In this case, the Lunar Probe has a shorter travel distance compared to the Milk Blue. The difference may seem minor, but it can greatly impact the feel and responsiveness of the key press. Gamers who prioritize fast response times may prefer the shorter travel distance of the Lunar Probe, while those who enjoy a more substantial key press may opt for the longer travel distance of the Milk Blue. Ultimately, the choice between the two switches will depend on personal preference and typing style.

Typing experience

Overall, when comparing the two switches, the Gateron Lunar Probe linear switch provides a smooth and stable typing experience with a subtle sound profile, making it ideal for those who prefer a quieter switch. On the other hand, the Outemu Milk Blue clicky switch offers a tactile feedback with a distinct click sound, catering to those who enjoy a satisfying audible response while typing. Both switches have their own unique qualities that cater to different preferences, so it ultimately comes down to individual preference when choosing between the two. If you enjoy a smooth linear feel with a subtle sound, the Lunar Probe would be the way to go, whereas if you prefer a tactile clicky feel with a more audible sound, the Milk Blue would be the better choice. Remember to consider other factors such as your keyboard layout, keycap material, and personal typing style when making your decision.

Conclusion

To sum up, when it comes to choosing between the Gateron Lunar Probe linear switch and the Outemu Milk Blue clicky switch, consider the factors of bottom out force, feel, and sound. If you prefer a light bottom out force and a smooth, linear typing experience with a subtle sound signature, the Lunar Probe may be the ideal choice for you. On the other hand, if you enjoy the clicky feedback and tactile response of a switch with a different bottom out force, the Milk Blue switch could be the better option. Ultimately, your decision should be based on your personal preferences and typing style. Choose the switch that best suits your needs and enhances your overall typing experience.
