Our Verdict

Logitech MX Keys

Logitech K780

The Logitech MX Keys is a better keyboard than the Logitech K780 overall. It features backlighting, which is nice and is rechargeable instead of using batteries like the K780. Both use very similar switches, but the MX Keys' keycaps feel a bit better, and the keys are easier to actuate.
