Our Verdict
Logitech G604 LIGHTSPEED
Logitech G603 LIGHTSPEED
The Logitech G604 LIGHTSPEED is much better than the Logitech G603 LIGHTSPEED. The G604 is more comfortable, has lower click latency through its receiver, has a wider CPI range, and has many more side buttons. However, the G603 is better-built, and it's smaller, making it easier to carry around.
