Our Verdict
Logitech G603 LIGHTSPEED
Logitech G703 LIGHTSPEED with HERO Sensor
The Logitech G703 LIGHTSPEED with HERO Sensor is slightly better than the Logitech G603 LIGHTSPEED. Both mice have the same shape, and the G703 has RGB lighting. It has a slightly wider CPI range, a rechargeable battery, and it has RGB lighting. However, the G603 has Bluetooth support, and it's more portable because it has a compartment to place the USB receiver.
