Gateron Lunar Probe vs. Gazzew U4Tx

An in-depth look at the Gateron Lunar Probe and the Gazzew U4Tx switches—which one is the best fit for you?

Overview

When it comes to choosing a mechanical keyboard switch, the Gateron Lunar Probe and the Gazzew U4Tx stand out as popular options. The Lunar Probe features Gateron's dual rail mechanism for stable and consistent keypresses, offering a smooth and pre-lubed linear sensation with a subtle sound signature. On the other hand, the U4Tx combines the best of both worlds with a cleaner, refined sound profile that delivers a deep "thock" when bottoming out and quiet keystrokes when topping out, providing a sharp, satisfying tactile bump for a luxurious typing experience. 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 Gateron Lunar Probe and the Gazzew U4Tx have distinct characteristics that contribute to their sound profiles. The Lunar Probe's polycarbonate top housing creates a sharper and crisper sound due to its stiffness, while the U4Tx's proprietary Gazzew blend top housing produces a rich and deep sound because of its softness. This difference in material results in varying sound experiences for users, with the polycarbonate housing offering a higher-pitched sound and the Gazzew blend providing a deeper sound profile.

In terms of the bottom housing, the Lunar Probe utilizes a nylon material that produces a deeper and fuller sound profile, thanks to its softer nature and sound absorption properties. Similarly, the U4Tx's proprietary Gazzew blend bottom housing also delivers a rich and deep sound profile due to its softness. Both switches benefit from the use of materials that create a more rounded sound, showcasing the importance of the bottom housing in contributing to the overall typing experience.

Overall, while the housing materials of the Gateron Lunar Probe and the Gazzew U4Tx have differences in terms of stiffness and softness, they both ultimately aim to enhance the sound profile of the switch. The polycarbonate top housing of the Lunar Probe provides a sharp and clear sound, while the Gazzew blend top housing offers a rich and deep sound experience. Similarly, the nylon bottom housing of the Lunar Probe and the proprietary Gazzew blend bottom housing of the U4Tx both contribute to a fuller and deeper sound profile, showcasing how different materials can impact typing feel and sound quality.

Weight

The Gateron Lunar Probe linear switch has a lighter actuation force of 45 grams compared to the Gazzew U4Tx tactile switch, which has an unknown actuation force. On the other hand, the Lunar Probe requires a slightly heavier bottom out force of 50 grams compared to the U4Tx's bottom out force of 62.5 grams. This means that the Lunar Probe offers a lighter typing experience overall, making it ideal for those who prefer less resistance while typing or gaming for extended periods. In contrast, the Gazzew U4Tx provides a more substantial typing experience with a slightly heavier bottom out force. Therefore, users who prefer a stronger push feel may lean towards the U4Tx for a more tactile typing experience. Ultimately, the choice between the two switches comes down to personal preference in terms of typing feel and force requirements.

Travel distance

The Gateron Lunar Probe linear switch and the Gazzew U4Tx tactile switch have the same travel distance of 3.6 mm. This means that both switches will offer a similar typing experience in terms of the distance the keys travel from the top to the bottom. Users can expect consistent results in terms of keypress feel and responsiveness with either switch. Overall, the travel distance of both switches is identical, making them equally suitable choices for those looking for a smooth typing experience.

Typing experience

When it comes to sound, the Gateron Lunar Probe linear switch offers a subtle and smooth typing experience with a muted sound signature. On the other hand, the Gazzew U4Tx tactile switch provides a unique acoustic profile with a deep and rich "thock" when bottoming out, coupled with a whisper-quiet topping out sound. The U4Tx switches create a bassy and muted sound that adds to the overall typing experience, giving users a pleasant auditory feedback.

As for the feel, the Lunar Probe switch's tactile experience is not mentioned, but it is known for its stable and consistent keypresses due to the dual rail mechanism. In contrast, the Gazzew U4Tx switch offers a sharp and intense tactile bump with each press, ensuring a luxurious and satisfying typing experience. The sharp tactile feedback of the U4Tx switches adds to the overall tactile sensation, making each keystroke feel distinct and precise.

In conclusion, the Gateron Lunar Probe and Gazzew U4Tx switches offer unique qualities in terms of sound and feel. The Lunar Probe provides a smooth and stable linear typing experience with a subtle sound signature, while the U4Tx offers a deep and rich "thock" sound coupled with a sharp tactile bump for a luxurious typing sensation. Depending on your preference for sound and feel, both switches can provide a satisfying typing experience, ensuring that you'll get similar results in terms of quality and performance.

Conclusion

In closing, when selecting between the Gateron Lunar Probe linear switch and the Gazzew U4Tx tactile switch, consider your preference for typing experience. If you prioritize a smooth and consistent keypress with a light 50-gram bottom out force, the Lunar Probe is the ideal choice for you. However, if you value a refined sound profile with a deeper "thock" and sharp tactile bump, along with a medium 62.5-gram bottom out force, then the U4Tx may be better suited to your typing style. Ultimately, your decision should be based on whether you prioritize a luxurious and acoustically pleasing typing experience or a stable and smooth linear sensation.
