Honestly, I don't care much about Answer, it was just dungeon crawling, removing pretty much all of the day part, which are a good chunk of what I like in persona's games. I did it once and it was a fluffing pain in the butt, never touched it again.
P3P, on the other hand, while it removed the ability to move the avatar around, improved on a lot of parts of the game while reworking most of the social links to fit the FeMC (on top of giving her much more personality than the bland MC which they insist on keeping for whatever reason)
