Depends what you want really.

Xbox has gamepass which is miles ahead of what Sony had. Also lots of cloud gaming and cross compatibility with PC platform which is great if you play across multiple devices. Xbox controller is also better designed and more comfortable or if you want to use a keyboard and mouse then most of them will just work with an xbox. It also looks better and takes up less space.

PlayStation is good if you're into your third person single player story games. It also has a larger install base so you're more likely to find people playing MP on PlayStation but most major games are supporting Crossplay now.
