NAUi advanced diver is a dedicated course that includes bight, deep and navigation as part of the course among other information. It also is recognized from my experience as allowing the diver to go to 40m (130ft) without the need for another course.
PADI AOW is not a course in and of it self, one has to take a bunch of specialties to get the Advanced cert/recognition card, and unless you do the deep dive specialty it only is recognized for depths down to 30m.
Just realize there are other training options out there other than PADI and it is not necessary to stay with one organization to continue training/education.
It is interesting and astounding to see time and again how divers seem to have tunnel vision that only focuses on the singular organization they did there initial training with...for recreational dive training it is not necessary, for instance I am SSI open water, NAUI advanced, NAUI masterdiver, PADI rescue, PADI divemaster.
