In my (also naturally limited) experience, the quality of the teacher may or may not be higher in high school AP classes, but the rigor of the classes is typically higher at a reputable university. In particular (and relevant to your username!) I have to say that while my own high school AP calculus teacher was truly excellent, the AP calculus standards were markedly lower than the standards of the calculus sequence I TA'd at two universities.
