I always loved Adventureland, and still do (even if it's gotten a bit crowded and watered down). Second would be a toss-up between Frontierland and Tomorrowland. The former has always had lovely scenery/theming and nice shady areas. The latter used to be really cool, even when it was more retro than future. Lately it's just "meh" though.
Pandora at AK is amazing... So nicely done, and looks good both day and night. I'm not a "fan" of Pandora, so it's a little lost on me, but all things considered... A great addition. That said, I love both Africa and Asia. The theming is so amazing there as well.
As for Epcot, I used to like FW in the 80s and early 90s - but it's been all about WS since.
