For argon to really work, you need to flush the suit with argon before diving, and get out the air. So you need to carry another tank to do the flush.

Sulphur Hexaflouride is a REALLY bad green house gas. ...
Argon makes sense when you are on Trimix since you don't want the high thermal conductivity of Helium in your suit, but studies have shown it make very little difference over air. The problem is perspiration increases the thermal conductivity as the humidity in the suit approaches 100%. That problem would exist with any gas in a drysuit.
Idk, 20% seems like a pretty good advantage...
