the xbox controller is a bit more sleeker to my liking, it probably had more comfort balance in mind than a playstation's controller
when i play street fighter with a controller, still dont own a stick curse myself, the playstation makes me push my palms into the edges a bit, and my hand gets really strained, sometimes to a point in which i feel carpal tunnel is about to come out of my hand and explode my face. the xbox's controller is a bit rounder like a gamecube controller and it doesn't pertrude into my hands that much. i did however own more playstation games.
