I've used both Argon & Air over the years. I personally believe that Argon's benefits are strictly psychological. I don't notice any difference.

It's kind of like the blind wine tasting studies done lately. They took a very mediocre wine (Two Buck Chuck) and told the subjects it was $90.00 bottle of wine. 80% of the test subjects, who were "knowledgeable" wine drinkers, perceived it to be an excellent wine. The Bottled water test, where all the water in the test came from a hose in New York City, provided rave reviews from the tasters who were told it was an exotic new water. Then there is the Vodka Blind test where regular Vodka drinkers chose Smirnoff as a top line Vodka and thought Grey Goose was a low end Vodka.

Do a simple blind dive test among divers with Air & Argon, and I suspect you'll find similar results.
