Logitech MX Master 4 vs Logitech MX Anywhere 3S

The MX Master 4 is the better pick for desk work: it is larger, has a thumb rest, a second wheel and eight buttons, and reviewers consistently praise its comfort over long sessions. The MX Anywhere 3S is the one to carry: at 99 g it is far lighter, tracks on glass, and its 4.8 rating from 5,900 owners is stronger than the MX Master 4's mixed scores. Build is premium on both, but the Master 4 suits medium to large hands and the Anywhere 3S suits travel and smaller hands.

• Choose the MX Master 4 if you work at one desk for hours and want a big ergonomic shape, a thumb wheel and plenty of programmable buttons.
• Choose the MX Anywhere 3S if you move between desks, coffee shops and bags, or have smaller hands and want a light mouse that tracks on glass.
