Even though you already purchased the PS4, I will still say this, in the event you decide to expand.
Disco and I have a PS4 and an Xbox One. She prefers the PS4, while I prefer Xbox.
PS has more exclusive games than Xbox. But Xbox has Game Pass, which lets you pay a low monthly fee and gives you access to tons of games.
PS4 Pro only upscales to 4k, while One X is in true 4k. Xbox also has a 4k Blu-ray player built into it.
4k aside, far as HD graphics, the two systems are pretty much the same. More or less, it comes down to which controller is most comfortable for you.
I own all 4 PlayStation's. Just started playing Xbox a few years ago. But I like the Xbox better myself. Unpopular as an opinion that may be.
I am sure you will not regret your choice in buying the PS4.
I am currently playing the Switch, which I am enjoying better than both of the other systems.
