Well, I guess it depends on what you consider the 'good stuff'. What type of campaign are you looking for? Are they big on the action or the roleplay? How do you like gobs of NPCs about? Each AP out there does good at focusing on a different theme, even if multiple ones are in Varisia.
A couple examples
We're partway through Jade Regent, and honestly it was great from the start. We gloss over a lot of the caravan stuff now, and skip random encounters, which helps keep up the pace. It is definitely Tian-Xia themed and even from the get-go hands out Tian treasures. There's also a lot of travel, especially in very cold areas.
I'm running a Crimson Throne group, and my players seem to be enjoying themselves. The first few chapters are really good, and there are lots of GM notes to help out for some of the 3.5 adjustments. It is heavy on the urban side for the first several chapters but don't be fooled, at least two chapters take you out of the city for some railroading.
A different group is playing Serpent's Skull and that's had quite a bit of fun as well. It's heavily jungle-based and very different from our Crimson Throne campaign.
