Our Verdict

Logitech G502 HERO

Logitech G903 HERO

The Logitech G903 HERO is slightly better than the Logitech G502 HERO, but they have the same sensor. The G903 is wireless, and it's better suited for those with small hands using the claw or palm grip. However, the G502 is wired, feels better built, and is more comfortable overall.
