Our Verdict

Logitech G915 LIGHTSPEED

Corsair K100 AIR

The Corsair K100 AIR and the Logitech G915 LIGHTSPEED are low-profile mechanical gaming keyboards. The Corsair is a bit thinner and offers slightly better gaming performance with marginally lower latency and a higher maximum polling rate of 8000Hz. It also allows you to program macros to every key, while the Logitech keyboard only allows macro programming on dedicated keys. On the other hand, the Logitech is available with linear, tactile, or clicky switch types, while the Corsair is only available in a tactile switch type.
