Logitech MX Master 3S excels for productivity with 70-day battery and MagSpeed wheel per Logitech data while Razer DeathAdder V3 wins gaming with 59g weight and 30K DPI sensor per Razer specs. The MX Master 3S trails in raw speed but leads in workflow features compared to the lighter DeathAdder V3. This is a close call depending on primary use.
