The Best Logitech MX Master Mouse in 2025, MX 3, 3s, or 4?

The MX Master 3 [https://geni.us/SJD0VR], 3S [https://geni.us/DtmB], and 4 [https://geni.us/INK9h] look nearly identical but the differences matter more than you think. The older models have that sticky rubber coating that gets worse over time. The 4 fixes that with matte plastic and adds a haptic action ring that replaces the old gesture button. If your 3S still works keep it. If you're buying new the 4 makes daily work noticeably smoother with better materials and actual repairability. This breaks down what changed between each generation and which one makes sense depending on what you need from a productivity mouse.
