Our Verdict
Logitech MX Master 3S
Keychron M6
The Logitech MX Master 3S and Keychron M6 are wireless mice with similar ergonomic-style shapes. The Logitech is designed for work use. It has noticeably better build quality and build materials. It also has a gesture button on the thumb rest, which the Keychron lacks. Additionally, its scroll wheel can automatically switch between notched and free-scrolling modes, while you need to toggle between scrolling modes on the Keychron with a button. That said, the Keychron is noticeably lighter and has much better sensor and click latency performance, making it a much better choice for mixed productivity and gaming.

Logitech MX Master 3S vs Keychron M6: Main Discussion

After having tried both mice, I would like to point out that for the “main differences - work” the weight of the mouse does not play a factor in the rating (unlike for gaming). However, for office workers that work 8 hours a day on the computer, a lighter mouse really does have an impact. I’m curious as to know why the weight of the mouse is not considered for work purposes. For myself the weight alone puts the Keychron over the Logitech especially for extended work usage (without considering build quality materials).
