Best for

What will you mostly use it for?

The R99 is the gaming-focused pick here, with its specified 8000 Hz polling rate and SOCD support, and it has the travel edge based on its lower listed weight and larger battery. The S98 takes the office, programming, modding, and content-creation picks, combining a compact numpad layout with a display, knob, USB pass-through, and more mounting options. For buyers who want a conventional full-size layout and prioritize wireless battery capacity, the R99 remains a clear alternative. Both offer the same broad connection modes and hot-swappable switch support.
