I use my Series X a lot more than my PS5 overall, mainly because of Gamepass and partly because it's just easier to boot up and play for a bit especially with Quick Resume which is incredible. I've also found it much handier than using my PC for certain games that are better played with a controller on the couch (main reason i got it!).
Going forward I'll use my PS5 for AAA's that you have to pay for/aren't on the X and the Series X for... well... whatever's on Gamepass. Mainly cause the PS5 does feel like a better next gen experience for the big games.
Basically, they uh.. kinda.. complement each other quite well and although I'd pick a PS5 if I only had to choose one, I'm really glad I have both cause they're both awesome in their own way.
Wait, I mean, feck microsoft lolz
