Playstation sucks... re-chargeable controllers were a massive flaw!^/s

If you mostly play multiplat games I don't see how you'd regret it. Honestly that's most games that most people play anyway. Plus it's been pretty rough the last couple years but when MS does (hopefully!) start dropping all of these exclusives they have in the works each one you're interested in is a $70 game you won't have to buy.

I personally only pick up my PS5 when a new exclusive comes out and I think the controller is cool but massively overrated. I'd like it a lot better if they'd crammed those cool new features into the DS4 form factor.

If you're interested in those PS5 exclusives though, and not just the Sony ones but FF and such too, it's definitely worth picking one up eventually. Looks like we're going to start getting more games that are actually made for the current gen this year so it's a good time to pick them up I think.

I've noticed that the GUI looks much sharper on PS5 as well. That's just how it is. For games though you really have to take it case by case. XSX is marginally more powerful than the PS5 but it ultimately comes down to what the devs actually do the work. And I don't mean that it should be better on XSX but it should be equivalent. It may be an HDMI cable as others have said or it could just be a game where the devs didn't optimize the Xbox version like they did the PS version. Callisto Protocol for example.

Also, check if maybe Xbox version is in performance and the PS5 version is in quality mode or something like that.
