I guess since you called "PS4" that you also mean Xbox One.
As a PC player, I only get consoles for exclusive titles, so I find the PS4 better and have it with me.
So the PS4 has more players in Europe, the Xbox is more popular in the USA and Nitendo consoles have the most players in Asia!
I would simply follow my circle of friends, if everyone in your circle of friends has a PS4 and you are the only xbox player, then that is not an advantage and you can only play games on which you can play with all consoles!

Ah, my circle of friends, everyone to gamble incompetently. 😪
Okay, I would buy the PS4, since the PS4 is generally more dominant in Europe! I think the best is the PC, but it's a matter of taste!
Because I can continue to play my PC games there
Do not find either console better.
The PS4 has more interesting exclusive games
The Xbox has the better controller and better online platform.
I have a PS4 myself but it was more of a bad buy since I hardly use it to play.
Most of my friends have an XBox, so it would be nonsense to buy another console. I also personally find the XBox menu more user-friendly.
Have both, just it is very sad that I have only one in my circle of friends who would like to play, but this one has no PC and Ps4 games no longer fit our current taste. Annoying.
