Guess I'll chime in here...
As a little background I learned to weld in high school around 2001ish. We did the OA-stick-mig-tig route and I guess that's why I feel it's best (I will elaborate a bit later). My dad had a lincoln ac tombstone at home that I used a few times then he bought a little harbor freight 120 mig eventually specifically for sheet metal work and I didn't care much for it.
When I was around 20 was when I first got into industrial maintenance and have been doing it since. My first job they had a couple lincoln tombstones with the big crank on them and I did a ton of welding with that in the couple years I worked there. My next (and current job) had a giant 3 phase lincoln welder that I believe was a 3 phase motor coupled to a dc generator and I did a ton of welding with it. 7 or 8 years ago I bought a lincoln idealarc tig/stick machine for myself and have built quite a few home projects with it. A few years ago we got a mig at work (xmt with a wire feeder).
My point is, in high school I wasn't great at stick but could get by. I at that time thought mig was great, but until recently didn't have a lot of exposure to it so I became quite proficient with stick. I still feel far more confident in my stick welds as it's difficult to make a bad weld look good. That's the problem I see with learning (from knowing nothing about welding) with mig, and the main point of my story- If you don't know what you're doing you can easily make bad welds that look good and you think you are the greatest weldor in the world and you will tell your buddies to bring over their 25k gooseneck trailers over so you can repair the frame for them.
Some here may remember that a few months ago I purchased a miller multimatic 215 so I could have mig capabilities at home for thinner work where tig is just not practical. I am quite happy with it and it has the power to cover most of my needs but I have every intention of keeping my stick welder for thicker stuff just because I am still more confident in my stick abilities... maybe it's because I'm out of practice with mig, I'm not sure.
Also, correct me if I'm wrong, but mig was not developed for it's superior weld quality, it was because it's cheaper to run and faster so for production work there is a huge cost savings.
Wow that got long fast, If you made it through thank you for reading
