What a problematic transplantation I am having (i.e. moving from Malaysia to The Netherlands).

All my diving gear sitting as unclaimed air cargo in Schipol (due to crap organization from my employer-services

).
Anyways.....the first diver I met here (an advanced GUE OC tech-diver) swears by the use of Argon in his drysuit. Until now, I had the impression there wasn't a notice-able difference (for CCR'rs).
I have yet to even don a drysuit.
What are your thoughts and comments on this?
