Our Verdict

Logitech G PRO X TKL

Logitech G515 LIGHTSPEED TKL

The Logitech G PRO X TKL and the Logitech G515 LIGHTSPEED TKL are similar wireless gaming keyboards with comparable performance and TenKeyLess form factors. The standout difference is that the G PRO X TKL is a standard, high-profile design and uses GX mechanical switches. The G515 LIGHTSPEED TKL, on the other hand, is a low-profile keyboard that uses GL low-profile mechanical switches. It provides a slightly better typing experience with better factory lubing on switches and stabilizers. It also has more acoustic material inside the case, making it considerably quieter.
