What sort of game are you looking for? Those adventure paths are very different from each other.
The only one I've run is Reign of Winter, which we all enjoyed. It is very episodic, and one trip takes you to early 20th century Earth, which is not to everyone's taste.
My comment on the others are just based on reading them (in some cases, quite a while ago) except for Strange Aeons (so I can't comment on that one).
Carrion Crown is very horror-influenced, which was a plus for me, but came across as a bit too much "monster of the week". It's like the brief was "write an adventure about werewolves", "write an adventure about vampires" etc. The first adventure looks really good, however, and the last one looks intriguing as well. I just think it seems to drag in the middle.
I love the first half of Serpent's Skull, as lost cities, jungle exploration and survival are themes that I like. The first adventure seems to get a lot of love from people who have played it. The second half looked okay, but high level dungeon crawls don't interest me much. If I ran it I'd probably end it early.
Hell's Rebels has an interesting premise, but seemed too much of a railroad to me. I appreciate adventure paths have to follow a set path, and a published sandbox version would have to be massive, but there seemed to be no sense that the player characters were driving events. I think it needs players who get very invested in the plot, so wouldn't be a good fit for my group.
Hell's Rebels is perfect if you enjoy multiple roleplaying opportunities and allowing your group several paths by which they can bring about a solution. It needs some work in places (but most APs honestly need a GM tweaking things) and the order of things can be altered to make it work better, but it still is quite enjoyable.
Reign of Winter is a lot of fun if you want a winding crazy adventure going through multiple worlds. Again, some parts of it could use some adjusting (for instance, the whole thing with Norgrimm works better if you have the group go to the Woodwife to enchant the hide, and need to go to to destroyed church of Desna to get components needed before ultimately holding the ceremony in the circle of summer) and due to the lack of towns and cities for the PCs to go to, it is a good candidate for the Pathfinder Unchained Automatic Bonus Progression rules.
Serpent's Skull, Carrion Crown, and Strange Aeons all need a bit more love and GM work before they can be effectively played.
