A:Answer It depends on your preferences, coming down to exclusives games or what you want to get out of a gaming console. The Xbox one X is no doubt the winner of the two top powerful gaming console out there in the market. It beats the pro and performs really well. And it will serve you well on that LG OLED 4K TV. The PRO is nice too, if you going to upgrade to an X, i say, why not, if you don't mind sparring 499 on a console, when it won't be long until the next Gen console is going to be announce. The investment in xbox one x is worth it along with that LG OLED 4k TV. The pro can do the same, but not outputting true native 4k.
