There are great instructors and there are awful instructors. Most fall somewhere in between. That being said, is a PADI instructor better than NAUI or vice versa? It depends on the instructor. Should recovering an unconscious diver be taught in an OW class? Absolutely. If there is a .0001% chance that the unconscious diver might live if rescued it is still better than a flat zero. To further my point, it is not an "unnecessary" skill as some have said here. Having the tools, even if they're rusty, are better than no tools at all. Yes, divers should practice emergency ascents and buddy breathing, but the number that don't probably outweigh the number that do. That being said, they are still tools in their boxes. Why should the recovery of an unconscious diver be any different?
I respect both agencies. I really do. I have friends across the spectrum of dive agencies. There are good, bad, awesome, and terrible in each. If there is any one factor that distinguishes one agency from the other is the training material required for the course. One cannot compare the PADI instructor manual (which is slightly thicker than the NAUI DM text) to the many course materials required by NAUI for theirs. Add to that PADI's definition of Master Diver (not DM) to NAUI's. Five specialties and you send $25 and get your MD card? Really? No test? Its a BS card that says nothing about one's actual diving ability. For example - buoyancy card, photography card, fish ID card, AD card (only good to 90'), and deep diver (that gives you NAUI's AD 130' limit) - and you can be a MD?! NAUI's MD requires a test and is basically DM without being commercial. Big difference.
Compare the swim quals for each to be an instructor and there's no comparison. NAUI also requires massive study in the science of diving. Most PADI divers can't explain Boyle's Law, ambient pressure, or even how a first stage works. Scuba is 90% science and 10% swimming.
One last point: NASA, Disney, the US military, and other educational institutions use NAUI exclusively. It has little to do with cost or popularity - PADI would win hands-down there. It has everything to do with education and textbook studies. "Dive Safety Through Education" is more than a catchy motto to NAUI, and its curriculum is intense. I would put an average fresh-out-of-school NAUI instructor's knowledge against the same level PADI instructor's any day of the week. That's not bias -- its fact.
