Yes! The IB is worth taking, but it's not for everyone. AP is fantastic, but it offers something very different from the IB.
What is it that you're looking for in your experience?
How hard are you willing to work?
Are you a self-motivated learner?
What are your goals related to these programs?
I'd encourage you to ask yourself these questions and answer them very honestly. The IB diploma programme is a two-year commitment. AP coursework is a yearlong commitment.
The best program is the one that addresses your goals and fits with your expectations. Universities would rather see a rigorous course load with strong grades rather than one with mediocrity and/or switching around.
As an educational consultant, I'm asked this question often. Only YOU, I'm afraid, can answer it "correctly" for you. I am willing to continue the discussion and answer more logistical questions, if you'd like however.
