Our Verdict

Logitech G915 LIGHTSPEED

Logitech MX Keys

The Logitech G915 LIGHTSPEED is better overall than the Logitech MX Keys, but their differences come down to their uses. The G915 is a wireless gaming keyboard with mechanical switches, full RGB backlighting, and dedicated macro-programmable keys. Also, it has much lower latency to provide a more responsive gaming experience. The MX Keys is designed for office use with very quiet scissor switches, a great typing quality, and Bluetooth pairing with up to three devices at once.
