Honestly I do not see much difference between the original PS5 and the pro, if it is as you mention, what it offers is not so much, if it is true that you get 120fps, but as you say it serves more for competitive and I do not consider myself a very competitive person except in FIFA.
The disk drive thing already seems to me to be a no shame haha, it is fatal that the unit is outside connected by a cable, a carelessness and you break that. The digital era is coming and it scares me too.
Good post of the PS5 Pro, this information is very useful.
