Our mig is our workhorse. My Son just feels very comfortable with it. The tig I got him two Xmas' ago just sits because he is so busy building his car he doesn't have time to spend learning to use it.

I think that generally Mig is a faster process where you are making lots of long welds, and Tig is a neater (perhaps stronger) process for those things you want to look super pretty.

At some point our Tig may be used more and more (I hope )
