Our Verdict

Logitech G PRO X TKL

Logitech G915 X LIGHTSPEED

The Logitech G PRO X TKL and the Logitech G915 X LIGHTSPEED are mechanical gaming keyboards with comparable raw performance with a few standout differences. The G915 X is a wireless, low-profile model with a full-size layout, while the G PRO X TKL is a wired-only model with a taller, standard profile and a more compact tenkeyless form factor.
