Xbox Elite Series 2 is quite possibly the best controller EVER
You’ll struggle going back to normal controllers where you cant trigger lock or use the rear flappy paddles to program to buttons. I have LB, RB, X, A programmed. Basically in shooters, i can reload, jump/vault/interact, throw grenade etc without taking my thumbs off of the move and look sticks. If you play online shooters and want to give yourself an edge, get one.
