XBOX has a really nice GUI/dashboard so jumping into using the console won't be an issue. Even though the PS5 controller was a big improvement from the PS4, IMO, XBOX still has the superior controller. I wouldn't assume any noticeable dropoff in graphics, but I do play different titles on each. Game Pass is worth every penny, and probably more if you game on PC as well.
That having been said, if you are wanting a disc version PS5 let me know.
