I took both and they are about the same except at the uni you do everything in 10 weeks as opposed to 10 months like in high school. If you take the test and pass you can ditch the first phys class at the university, or go on to take the honors one (which is not required but recommended).
Also you must note that "physics" isn't really about mechanics as you study in your high school class. You take mechanics first quarter, then perhaps take another advanced mechanics class (covering Lagrangian mechanics, etc) 3rd or 4th year and that's it. Most of physics is on electrodynamics, quantum mechanics, statistical physics, waves/optics, etc.
So the question is not whether you "like AP physics", the important issue is how you will adapt to the new material. If you are a savage beast in this class now, I wouldn't worry. I am pretty dumb and was still able to go through any phys topic, its a matter of interest.
