Ps4 Pro models and differences?

I'm currently playing on the normal Ps4 Apex and these little jerks and etc. Annoy me.

Since the Ps5 is pretty much out of stock, I wanted to get a Ps4 Pro in the hope that it could have the stable 60 FPS.

But are there different Pro models that have different levels of performance or are they identical in terms of performance?

How do the Pro models differ?

Better wait and get a PS5 as soon as they're available again! Believe me, buying a PS4 now is really not that smart!

Well the Ps5 costs twice as much, and I think I'll get rid of the Ps4 pretty quickly because it loses little value and is still popular

Oh, forgot to mention that I would buy the Pro used for under 200 euro

With the PS5 you can play PS5 AND PS4 games! Don't forget that. So you would have a much larger selection of games.
