Works both ways Xbox controllers have a share button now aswell

Like the other redditor said it will come down to what you want to play I don't have much knowledge of the switch but the PS4 also functions as a multimedia device Netflix, YouTube, etc so it may be worth looking at that aspect as well to get the most use out if it

Xbox games pass is very good if it's your first Xbox not so much if you own a lot of games from previous generations (I do but subjective I'm also 35 so I own a lot of Xbox titles. Games such as halo really don't appeal as much when I played and owned the original). Ps5 is an amazing console with a mind blowing controller and excellent exclusives which will eventually come on to PC. My recommendation is to get a Ps5 and a PC. Xbox games being available for PC makes the Xbox a bit redundant in my opinion. But it really does come down to the games and Thier really isn't many next gen titles as of yet.
