Is the IB better than AP?

I attended an international high school in Tokyo called CAJ, and took Advanced Placement (AP) credits because it was an "American" system preparing mostly American kids for applying to American universities.

I had heard about how other international schools were doing IB, International Bacclaureate, but was never familiar with what the program entailed.

This article in the NYT was very interesting.

Perhaps I should put my kids in a high school with an IB program?
