One con for de for you may be the cost of books on top of the cost of the class. Depending on the book you may find a cheap copy but some of them have a connect or access code that if needed can be over $100. We don’t pay for de classes or rentals but pay towards AP tests.
Not sure about your school but at our high school those are all full year ap classes and 1 semester as de classes. A pro is if you don’t like the class you finish quicker. A con is if you love the class is it doesn’t last as long. A pro for de is you could take 4 de (two a semester) and just 2 AP.
When/where are the de classes offered? How does it fit into the rest of the schedule.
One college my daughter applied to will give credit for AP English or DE English Composition. However if you want to do the honors program they will not count either one. While I’ve only heard of it at the one school it could be something to ask about.
tip for de - save course descriptions and syllabi - some schools may ask to see them
