A&P I is a lot of memorizing, but it will build the foundation for more bio classes. Having a good professor will leave you with more knowledge and a better base. I thank God every day that I had the professors I had now because had I had ty ones I would be struggling in Grad School. If this class is something you'll need in the future I would go with the good professor.
If they're good and you pay attention, who knows you might not need to study as much. With the second option, you are going in blind, but the professor could be good.
But you also didn't mention...can you take it in the Fall/Spring and have the full semester? That's what I would do.
