The only setting I don't have is Castle Whiterock, and in my purely subjective opinion I would go with ...
1- Ptolus - So much detail (love the huge map), story hooks, support and amazing characters that its a GM's dream. Its also more open ended than many of the AP's.
2- Crimson Throne - The best of Paizo's APs
3- Rise of the Runelords - Classic "We be goblins, you be food!"
4- Slavelords - I absolutely LOVE both the adventure and the Grim Tales rule kit.
