Doesn’t seem to be any surprises in the not compatible section. As mentioned before, being able to play BC is a nice bonus. but the reason you buy consoles is for new games and expierences.
One of my main reasons for going with the XSX over PS5 at the start of the gen is having BC with all three of MS other generations, among other things.
As mentioned many times, what some might consider a nice bonus others might see as a driving factor. Niether side is objective, but it is always a good laugh to see people try to act like their opinion is fact (one way or the other).
