Head-to-Head Breakdown

Logitech MX Master 3S
- MagSpeed scroll wheel switches seamlessly between tactile ratchet and infinite free-spin. Switch and Click and 10BestOnes call it unmatched
- Dedicated horizontal thumb wheel for spreadsheet and timeline navigation praised by Hardware Canucks
- 90% noise-reduced quiet clicks ideal for shared offices and video calls. Switch and Click
- 70-day battery life eliminates charging anxiety. Hardware Canucks
- Logi Options+ software enables deep per-app customization and gesture controls. 10BestOnes
- Soft rubberized coating notoriously degrades over time, turning yellow and sticky. Switch and Click, Hardware Canucks
- 125Hz polling rate makes cursor feel sluggish compared to modern mice, completely ruled out for any gaming by Switch and Click
- 141g weight is too heavy to comfortably lift and reposition repeatedly. Switch and Click
Keychron M6
- PixArt PAW 3395 sensor with 1000Hz polling delivers flagship-tier tracking at a $50 price. Cameron Dougherty Tech
- Only 78g, nearly half the MX Master's weight, making it viable for both gaming and productivity. Switch and Click called it 'endgame'
- Includes both side scroll wheel and infinite free-spin top wheel, rare at this price. Switch and Click
- Triple connectivity: Bluetooth 5.1, 2.4GHz dongle, and wired USB-C. Keychron
- Aggressive rear hump drop-off prevents relaxed palm grip for larger hands. Switch and Click, Cameron Dougherty Tech
- Side scroll wheel sits too high and feels scratchy; tilt-wheel increments impractically small. Cameron Dougherty Tech
- Plastic build feels cheap compared to premium competitors; silent switches lack tactile feedback. Switch and Click
The Verdict
Our Bottom Line
The Logitech MX Master 3S won because no other mouse in the field comes close to its scroll system. The MagSpeed wheel, which flips between precise tactile clicks and buttery infinite free-spin with a flick, remains the single best scroll wheel on any mouse, period. Switch and Click, Hardware Canucks, and 10BestOnes all singled it out as the defining feature.

- You spend 8+ hours daily in spreadsheets, documents, and creative apps
- You work in a shared office or take frequent video calls (quiet clicks matter)
- You never game on your work mouse, the 125Hz polling rate is a dealbreaker for gaming
- You want one mouse that lasts 70 days between charges and never think about battery
- You're invested in Logitech's ecosystem and want app-specific button customization
Keychron M6
The Keychron M6 won the value pick because it packs specifications that have no business being in a $50 mouse. The PixArt PAW 3395 sensor, the same chipset found in $130+ gaming mice, delivers 26,000 DPI and 1000Hz polling. Cameron Dougherty Tech was visibly surprised during testing at how responsive the cursor felt compared to mice twice the price.
- You want one mouse that handles both work and gaming without compromise
- You're price-conscious but refuse to sacrifice sensor quality
- You have small-to-medium hands, the M6's shape suits this size best
- You want the lightest possible mouse (78g) for all-day comfort
- You switch between devices constantly. Bluetooth, dongle, and wired gives maximum flexibility
