IIRC 106 millions PS4 have been sold in total, 20ish of which are Pro.but the Pro and One X, as well. Which I think a lot of people have now?
For xbox numbers are more ore less the half, that's why MS has stopped announcing them.
Anyway, I recently went from PS4 to PS4 pro and I can tell you there's little to no difference unless you have a very expensive 4k TV with processor dedicated to supersampling. And I don't. It was a gift for me, I wouldn't recommend to upgrade a ps4 to ps4 pro, just a waste of money: same hardware except for GPU.
One X should be better, they say.
I haven't bought it at all because everybody I know and has it says frame rate is a mess, often unplayable on standard ps4.As for destructible environments, I haven't played Control much (about 20 minutes or so, maybe an hour) so I can't speak to any issues. I'll take your word for it.
I can guarantee that in 6 years the only game I've played that had serious problems was days gone on standard ps4 (and apparently control). Everything else was absolutely from "not a biggie" (TW3, bloodborne) to great (RDR2, GOW) for console standards. This gen has been way smoother than the last one in terms of fluidity.
