"What is everyone's opinion about that extra expensive non-ethanol super?"
I have never used it in any of my Alfas through the years, except when that was all you could get, period. I suppose, if you have enough money, however...
Have never had a problem with using just plain premium in the original engine 91S (185k miles) and the 94LS (110k miles), and either regular or midgrade in the Milano (100k miles). All bought at Fred Meyers. The only additive I use is Techron every few fillings, just to keep the fuel systems, valves, and injectors clean. Seems to work, have had zero problems with injectors, etc.
If the car has old gas in it, yes, you could use some Stabil once or twice, but not regularly necessary once you start driving the car. If the car is driven regularly, no problems with old gas, which I've never worried about anyway, never raised it's ugly head. Modern gasoline is pretty good for that anyway.
