Our Verdict

Logitech G915 LIGHTSPEED

Razer BlackWidow V3 Pro

The Razer BlackWidow V3 Pro and the Logitech G915 LIGHTSPEED are two fantastic wireless gaming keyboards. Even though the Logitech's low-profile switches have a shorter total travel distance and lighter operating force, the Razer provides a much better typing experience. The Razer also has better build quality, and all its keys are macro-programmable, while the Logitech only lets you reprogram the dedicated macro keys.
