My advice is to do what you feel will best prepare you for taking the AP Exam and concurrently giving you the best opportunity to perform well (basically, which will give you a better grade). Since both seem to be Honors Level classes, they will most likely look the same on the transcript. At the same time, taking a class that has more of a college feel to it might prepare you better for college level course work.
In my experience, students who take AP Calc and are eligible to receive college credit will still re-take Calc I in college just to get a feel for college classes. Plus, they come with previous knowledge and have a opportunity to receive a high grade.
