Of the two: The Xbox One X is the obvious choice in terms of power, and 3rd Party Games will definitely look better on it, but in terms of games - as much as I love Halo - the PS4 is doing leaps and bounds better than the Xbox One.
Frankly, If I had to pick one or the other, I'd go for the PS4 Pro. The games wont look *quite* as good, but I'd rather play some of those amazing first party titles, than have a few more pixels.
