While there is a contingent of restorers that prefer gas, there
are still many many that use MIG or TIG.
I don't agree with the underlying sentiment of the above statement
that sort of makes it sounds like "all the best guys use gas and
the lesser folk use MIG".

Any kind of welding that produces a weld of a different thickness
makes it somewhat tougher to reshape the panel with hammer and dollies
after. However, "tougher" is not impossible, and this problem applies
to just about any form of welding.
Normally after the welding is done the only bodywork left
is grinding flat, and no weld can resist the awesome power
of the angle grinder. ;>
