Our Verdict
Logitech G PRO X SUPERLIGHT 2
Keychron M4
The Keychron M4 and the Logitech G PRO X SUPERLIGHT 2 are lightweight wireless gaming mice. The Keychron has an unusually small shape that's designed specifically for use with a fingertip grip. In contrast, the Logitech has a much more conventional shape that's suitable for a wide variety of hand sizes and grip types. The two perform similarly otherwise, but the Keychron is significantly lighter thanks to its size, and the Logitech supports a higher maximum polling rate of 8000Hz.
