I'd argue you on that. I've got a Millermatic 175 220V MIG and I still turn to my stick welder for the heavier stuff. Thinking back on it, though, I'd agree that most of what I mentioned you could probably use the MIG for. However, when I need the penetration and want to lay down a heavy bead, stick does a better job than MIG. A 1/8" or 3/32" rod is going to go quite a bit faster than building up a weld bead with wire... JMHO...
