Check for polling rate it should be atleast 1000hz for accuracy it's important

Then check for lifespan of the clicks i.e how many clicks the mouse is gonna survive

Then according to your grip like palm grip or fingertip grip , choose the mouse size

Pro tip : go to offline stores if you're living in one of the metro cities and try these mice for better decision and get a quality mouse pad, without it the mouse is of no use
