MX Master 4 or MX Master 3S?
Do haptics and newer workflow controls justify paying more?
Current evidence-based answer
Research more before upgrading.
The MX Master 3S costs $40 less at the verified Canadian prices. The MX Master 4 adds customizable haptic feedback and newer Actions Ring workflows, but the evidence does not yet establish that those features improve enough real work to justify the premium for most buyers.
