Do a Google of this news group. This has been hashed out pretty well.
My take on the sum of the debate is that while there was no clear
winner, O2/Acytelene was considered to be the defacto standard with TIG
considered by some to be either ecceptable or better. MIG on the other
hand was considered to be acceptable only when used by someone with
considerable experience using MIG on thin material.

Then there is the debate on which rod is best.
