I found this thread of discussion of IB vs AP on The Princeton Review site. As you can see, each program has its supporters. The fact is that few people have experinces on both side to give an objective comparasion.
A couple of years ago I was in your position of deciding whether to send kids to a school with IB or a school with AP. I posted the same question on some discussion board and get 0 reply. Hopefully you have better luck.
