Thanks fellas I guess the choice is clear. I was always leaning towards X1X but reading the internet always makes it seem like doom and gloom for Xbox lol.
Yeah they're still getting burned for 2013 despite all the gains they've made. MS's infrastructure is fantastic for Xbox Live, its controller is better, and most games will look better (especially ones without specific enhanced patches, like smaller 3rd party games).
Plus PUBG is much better on the X than the normal console. I assume you have both an Xbox One and a PS4 already, but if you've played that at all I think you'll find the X version very enjoyable in comparison.
