Not OP, but I can say that PF2e is complicated only in comparison to something like D&D5e. Compared to D&D3.5e (which is what PF forked from) it's more streamlined.

I think streamlined vs complexity is a topic that should be discussed here. Complexity isn't a bad thing- Street Fighter is more complex than Mario 1. But that doesn't mean it's bad, obviously. PF2e vs D&D5e are similar. Both are great games depending on what sort of complexity you're looking for, and that's personal taste. For me, 5e isn't complex enough.

Its a little crunchier. However from the GM perspective its a lot better to run. The math behind the system is real strong, which isn't something you get from RP systems. Its not like PF or 3.5 where there can be massive power differences between characters.

Combat is a lot more interesting, its not just roll d20's burning down the HP of whatever you fighting. I tend to find that 5e battles seem very same-ish.

As a GM, PF2e is quite easy and simple. There's great tables for DCs. It's pretty easy to determine what skill to roll. Calculating your roll is super simple. Scaling monsters is easy and simple. Creating encounters of any level is easy.

As a player, I think it has a higher learning curve because of the new action rules and the vast amount of actions one can do, but personally I think it's a good thing :)
