The history of AADA is incredible . . . I attended when the NYC school turned 100 years old; so it was a big deal at the time. I don't know what the school is like nowadays. Nevertheless, I can say that all of us from my class learned a lot and have all had our share of success; in the ways we chose.
I tend to agree with 'PAB' who said it "depends on the facility the school employs" -- and every person responds to certain teaching styles differently.
We had some incredible teachers when I attended -- and some which were questionable. Nonetheless, from the 'questionable' and the excellent teachers you still learn something (i.e. how not to act as a teacher [if they are questionable]). And certainly, rough or difficult teachers are great for practicing 'rejection' and difficult directors, producers, etc. which you'll undoubtedly meet in your journey to a professional career in this business of 'show'.
If you're an actor, especially; anything you do in life is a potential learning experience. It is called "character study" and the world of human beings is your school.
All and all, whatever you decide and where you auditioned and get accepted -- regret nothing as it is all educational! And be kind, or at least, decent to fellow students, teachers, etc. as sometimes they turn out to be casting directors, directors, producers and others who may be helpful to you in later years!
My class at AADA included Billy Baldwin and a year ahead of us was French Stewart -- who was still in attendence when we started our first year!
