Our Verdict

Logitech MX Mechanical

Keychron K4

The Keychron K4 and the Logitech MX Mechanical are both wireless, mechanical productivity boards. However, the K4 will give you a more classic mechanical typing experience as it uses standard switches, while the MX Mechanical feels like a hybrid between a mechanical and scissor-switch keyboard thanks to its low-profile switches.
