The diffence in conductivity of helium and air is over 6 fold, between air and argon about 1.3 fold.
And this 1.30 factor is for STILL and DRY air compared to argon.
In reality, when diving the gas in your drysuit will not be still nor completely dry, so the theoretical 1.30 advantage is likely to be much LOWER in reality.
