Our Verdict

Logitech G903 LIGHTSPEED

Corsair DARK CORE RGB PRO

The Corsair DARK CORE RGB PRO and the Logitech G903 LIGHTSPEED are two similar-performing mice. The Corsair is a right-handed mouse with Bluetooth support. It has lower click latency, and a wider CPI range. However, the Logitech is an ambidextrous mouse that's lighter, has less CPI variation, lower lift-off distance, and more buttons.
