I prefer P2E generally. It's not the perfect system, but it solved a lot of my complaints I'd had with other systems. Combat is generally pretty fluid and feats for out of combat utility are nice.
Sadly p2e is going to be splitting up into three books later this year so they can purge OGL content from their core books. Good news though that means the hardcover books will get all the errata that's come out, and they're even reworking some of the lackluster stuff.
Glad you took the time to create this community. Hopefully it gains traction.
