Our Verdict
Logitech G305 LIGHTSPEED
Logitech G603 LIGHTSPEED
The Logitech G603 LIGHTSPEED is better than the Logitech G305 LIGHTSPEED. The G603 feels better built and is better suited for any hand-size with a palm grip. It also has Bluetooth support. On the other hand, the G305 is lighter and has a marginally lower click latency.
