You may know this already, but if not - if you have others to share the console with (eg kids, partner), I think it'll be worth going for the '5 just from that perspective.

Switching between games is a non-trivial (yeah yeah mock me, 1st world problems) thing on the ps4 in that the active game must be quit first, then the new loaded. You may not be on a suitable spot to quit either, far from save point. On ps5 (or xsx) it's supposedly a very quick alt-tab kind of thing.

So far, I'm kind of happy in secret that the rest of the family prefers the Nintendo :)
