Is ps5 worth it or should I stick with the good old XboxONE S?
If you had the money i would buy a ps5 or 4 in your place.
It depends on what a console has to do for you to make it "worthwhile".
For me personally, the Xbox is much more interesting than the Playstation (even though I had a PS for 20 years).
But at the moment you don't generally need a new console because everything comes out for the old one.
