What will you mostly use it for?
The Everglide takes the gaming category on its explicit Hall Effect, Rapid Trigger and high polling-rate feature set. The GravaStar is the more convenient option across office, programming and travel use, with its pre-built form and multiple connection modes. It also has the edge for switch experimentation because its listing specifies 3-pin and 5-pin switch support. For content creation, its described streamer effect and wireless choices distinguish it, while both models offer RGB.
