PF1 is swingy and CR unreliable (more so than 5E) so it's a stark difference. For me, I have so many years of experience with 3E/PF1 that its like a feature because combats are less predictable and thus more interesting. However, they require an experienced GM not to go pear shape on the table. So, I can see the attraction in balanced reliable CR which PF2 delivers better than any RPG I have played.
I'm about as experienced a GM as they get, but even I couldn't keep that reliably true in D&D3e at least; there were too many moving parts as you got above a certain level.
