Our Verdict

Logitech MX Keys

Keychron K3 (Version 2)

The Logitech MX Keys and the Keychron K3 (Version 2) are both wireless keyboards designed for productivity use. The Keychron is mechanical, and you can select from a wide array of low-profile switches to use in the board or opt for the hot-swappable variant to put in your own. Also, the Keychron is a compact 75% size, and it has two incline settings for better ergonomics. On the other hand, the Logitech is a full-size board that uses scissor switches that provide a lighter typing experience. It also comes with companion software, meaning you can remap buttons.
