Our Verdict

Logitech G915 LIGHTSPEED

Corsair K100 RGB

The Corsair K100 RGB and the Logitech G915 LIGHTSPEED are both fantastic gaming keyboards with different features. The Corsair is a wired keyboard with a USB passthrough, and the Logitech is a wireless option with multi-device pairing. They each have dedicated macro keys, but you can reprogram every key on the Corsair, which you can't do with the Logitech. The Corsair is available with two types of linear switches, while the Logitech is available with either tactile, clicky, or linear low profile switches.
