Our Verdict

Logitech MX Master 2S

Logitech G903 LIGHTSPEED

The Logitech MX Master 2S and the Logitech G903 LIGHTSPEED are both great mice but designed for different uses. The MX Master 2S is designed more with productivity in mind and has a comfortable, ergonomic fit with a thumb rest on the left side. It also has a horizontal scroll wheel and a slightly better-built quality, but unfortunately may be too large for smaller hands. The G903 is more gamer-centric with RGB lighting, two programmable side buttons, a much higher max CPI, and a smaller body that almost every hand size in any grip type can use.
