Sae’s palace. It was cool going in and cheating the games in your favor, and also Akechi joining you during the palace was pretty neat. 2nd place would be a tie between Okumura and Mementos. The space stuff was fun, and I thought the terrifying atmosphere of mementos was perfect for the Phantom Thieves last mission.

Kamoshida's palace was my fav because once beating it I felt so satisfied and glad that bastard will be paying for what he did. Also it's the first palace so that was my intro to this amazing game!

my personal favorite is the mementos depths. it looks amazing, and the music is one of my favorite palace themes. I like it for what it represents most of all, it's poetic in it's existence, easily my favorite palace.

Its tough, because while Sae’s palace was definitely my favorite, I was much more taken away at every turn by everything in Kamoshida’s palace since this was my first Persona game.
