Our Verdict

Logitech G305 LIGHTSPEED

Logitech G703 LIGHTSPEED with HERO Sensor

For most uses, the Logitech G703 LIGHTSPEED with HERO Sensor is better than the Logitech G305 LIGHTSPEED. The G703 is lighter, more comfortable to use, and has better performance due to its wider CPI range and lower CPI variation. Its build quality also feels better, and it has RGB lighting, which the G305 lacks. However, the G305 is smaller and more portable, and its ambidextrous shape makes it more suitable for left-handed use even though its side buttons are on the left side.
