I did the AOW course right after my OW also. At the time of certification of my OW I was very comfortable under water and the "shopper" in me figured, for an additional 5-6 dives, I couldn't rent the equipment for what I was paying for the course! Looking back I would have to agree that AOW is sort of a joke in the sense that none of the 5 specialties really advanced any skills as such. Well that is not all true, I really liked the navigation part.
As for the "deep" dive, I did the math faster at 100' then on the surface! It is was it is, and you will get out of it what you put into it. Did it improve my skills, maybe. Did it make me a safer diver, perhaps. Did I meet new friends, yep. I have never regretted the time, effort or money spent on diving. I live next to the St Lawrence River and have at my disposal some of the best fresh water diving in the world! That however is my opinion.
