Our Verdict

Logitech G502 HERO

Logitech G MX518 Legendary

The Logitech G502 HERO is better than the Logitech G MX518 Legendary. The G502 HERO feels better built and more comfortable for most people. Also, it has a lower lift-off distance and many more programmable buttons. However, the MX518 Legendary's feet glide better, and its sensor is slightly more consistent than the G502 HERO.
