But it would still warp.

It is why in the old days they used a string line and these days a laser to guide the welder where to weld next to correct the warping.

BTW: production gas metal arc welders were available before WWII. My welder mate, did his apprenticeship in the UK in the early 1950s and learned on a MIG at that time (as well as stick and gas).

A debatable point!

I can't see how, when using 1.6mm electrodes with the MMAW, that the TIG with its very slow rate of travel, would produce a smaller heat-affected-zone.

A faster rate of travel with the MIG (GMAW) would be advantageous; however; corner joints especially, demand a fast rate of travel, whether by MIG or MMAW.

I have all three types of welder and given the choice I think I would pick the MMAW first, with the MIG a close second. The MIG definitely first, if there were a few gaps to fill,
