What will you mostly use it for?
The S99 is the more specific gaming pick here because its listing names a polling rate, and its aluminum case distinguishes its materials. The F99 Pro takes the office, programming, travel, modding, and content-creation picks on the strength of its knob, battery capacity, lower listed weight, and stated customization tools. Both offer linear switches, gasket mounts, and wireless connections, so those shared features do not settle the choice. Consider the F99 Pro's south-facing LED and keycap compatibility note when choosing replacement caps.
