I think most pros would acknowledge that you’re wrong. Controlled on PC is likely what most pros do, though I don’t follow any so this is pure speculation. I’m an Xbox player, and I have one friend who plays PC. I am exponentially better in console only lobbies than pc lobbies. PC / MnK gets exponentially more benefits than controller.
if you are finding that you are often being beat by controller, then it’s either a console player using hacks like aim assist, or a controller on PC with better ping etc. Or you just don’t move around when you play enough, but I imagine that’s not the case.
