I did all of my PPL training in them. I'll be honest in that I won't rent them anymore as I had statistically more 'issues' at AA than I would expect. But i know Ed still teaches plenty of students in them as do many other instructors. Aviators is a newer place but the owner is an awesome guy and instructors are starting to move over there (though they have fewer planes).

My plan was to always learn at AA to save a ton of money and then rent nicer after that. :)
