PSN is not nearly as good as XBL from what I've heard, and being able to talk and play with friends is the biggest reason I play games as much as I do now, games are twice the fun with a friend. Not to mention the apps Xbox has, my family doesn't have cable right now and we use the Amazon Prime app like we would cable, big factor.
