Congrats, I've been here a long time and that's vying for the silliest fanboy post I've read
Power seems pretty similar, I think the way power can be redistributed in PS5 could be harder work for developers but could also close or even overtake the theoretical power difference.
To be honest, I'll likely buy both fairly soon after release since in terms of cost/hour of fun, they'll both be a bargain in the long run. If I have to pick one then unless there are some launch titles to sway me then I'd lean towards XSX purely for the backward-compatibility so I have more titles to play day 1.
