I gave zingbobco000 exp for his post because having started DMing live with Princes of the Apocalypse I can tell you despite my problems (up to 9 players per game) it was a much easier book to read and since you are above ground you can do lots of fun sandbox stuff that will come more easily to you. There's also the fact that deep below the Dessarin Valley is the Underdark. OotA takes place 30 years later so you can offer your players a "trait" system if they want to play their former character's kids.
OotA was much harder to read, plus they throw Insanity and a ton of NPCs at you out the gate. This doesn't mean it is worse. I think it is volumes better than PotA because it allows you to play each of the areas in a more subtle fashion. Both are great adventures and both have great re-play-ability due to their openness.
Thanks! Also, I totally agree with you and the kids thing is a pretty cool idea.
