I see no reason for Xbox if you have a PC. I have xbox game pass on my PC and it sits next to my PS5 connected to an LG CX Oled. It's just a big xbox that plays pc games, mods, pays bills and all of the other stuff PC's do.

If you want to see Playstation exclusives just Google GOTY nominees every year for the past 12 years and you'll find 2 or 3 almost every year.
