I'm confused as to why we would limit ourselves to only one good feature, and why value is not part of the equation. As an instructor I can get significant deals and I can informatively shop eBay/craigslist/yard sales, but if I were just a casual diver I would look for most of those features with good value. Value would also include service down the road.
Most divers do not get the chance to see how various regs perform under a variety of conditions. I was lucky enough to work for an Oceanic retailer when the Delta 4/CDX-5 was released. I bought it because it was cheap; I now wish I had bought at least one spare.
I think it has all the features you list in your poll, with the added feature of significant flow adjustment on the fly. In high current /scooter diving I can crank it down until it just barely gives adequate air but doesn't freeflow, if I end up deep I can open it up to just nearly freeflowing in dead calm.
I might have voted if there were three other options; flow adjustment, value and all the above.
