I would say that it’s mostly about balance- you don’t want to take only AP classes or only college classes. Look at just your high school classes, what is your most challenging option? AP classes. So, you should try to take as many as you can and will be able to do well in, and take the ones that you are interested in. Then, you should take college classes to complement your other achievements. Take college classes that would fill in gaps in your education (for instance, if some classes didn’t fit in your hs schedule, try to take them at your community college when possible). Also, consider taking college classes for which your high school offers no alternatives, or does not offer an AP course in. This way, you have a balance and good mix of challenging courses, both AP and college courses. It’s not so much as which one is better, but rather how you can use both of them together to present yourself and your academic achievements in the best way possible.
I agree with @katcollege! I’ve taken many college classes (so far) and will be switching to mostly APs for senior year. i think a balance is always good! The thing I like about college classes is that they will most likely transfer to in state public universities (out of state and privates are not guaranteed) and you do not have to take an exam just to get the credit. That being said, AP Credit is accepted pretty much everywhere. There are definitely pros and cons to both. I like that my local CC has classes that aren’t covered in the AP listing. So I was able to take biology without having to take AP Biology and I’ll take college anatomy and physiology, which there isn’t an AP class for that! So I think both are impressive. I would not favor one over the other 
AP Classes are preferred as they are standardized nationally(via AP test).
