Our Verdict

Logitech G915 LIGHTSPEED

Keychron K3 (Version 2)

The Logitech G915 LIGHTSPEED and the Keychron K3 (Version 2) are both wireless, mechanical keyboards with some key differences. The Logitech is a full-size keyboard designed for gaming use. That said, it has significantly better latency, dedicated macro keys, and companion software to allow you to customize your settings. On the other hand, the Keychron is a compact, 75% board better suited for office use. It has low-profile switches and keycaps, and it also comes in hot-swappable variants.
