In my opinion rescue diver is the most valuable certification a non-technical diver will ever get.
AOW is a pre-requisite for rescue diver for Padi. Over time you can gain all the AOW dive experiences without taking the course, but if you want rescue diver certification, you'll have to do the AOW course no matter how many dives you have done.
The pre-requisite is AOW or equivalent.
I don't see why any dive operation wouldn't accept 5 specialities (inc deep and nav) as an appropriate equivalent for AOW....
