Our Verdict

Logitech MX Master 3

Logitech G502 LIGHTSPEED

The Logitech MX Master 3 is outstanding for the office, while the Logitech G502 LIGHTSPEED is very good for gaming, though it performs well for other uses as well. The two mice are very comfortable and have ergonomic designs with thumb rests. They're both better suited for larger hands. That said, the G502 looks a lot more aggressive, with sharper edges, more buttons, and RGB lighting. You can use it wired or wirelessly, and it has a wider CPI range, a lower lift-off distance, and lower click latency. On the other hand, the MX Master features two scroll wheels, supports gesture commands, and can connect via Bluetooth.
