Maybe would have been fun to live there in the past, but my perception is that it's grown too much too quickly. Traffic is now horrendous, etc. And things are predicted to get a lot worse:
"The Texas A&M Transportation Institute has built sophisticated computer modeling of Austin's future traffic — and the findings are not good. The commute from downtown Austin to the northern suburb of Round Rock currently takes about 45 minutes during rush hour. But by 2035, the institute estimates, it will take two hours and 30 minutes to go those 19 miles."

All that said, it's a fun place to go for a game. Good food, good music.
Never been to FC either, but it sounds like a great place to live, especially if you have a family.
