I agree with @ucbalumnus that @rhandco’s is overstated. Many schools DO accept DE credits (just like AP credits), particular from in state colleges. Note that it does not mean it is automatic. It will depend on the school and also the course. Some college may set a limit on the number of credits to be transferred this way though. Taking AP exam as a back up plan only if needed as one may find out where to matriculate before the AP registration deadline. Also, CLEP is also available for the same purpose.
OP, the school would never look down on DE as it is actually at least as rigor as AP courses if not more. You don’t need to explain anything why you are not taking the AP instead. Why would one need to explain not taking easier course after all?
