+1 for Austin. My base salary is slightly higher in Austin, mostly due to moving to a later-stage company, though the salaries really aren't that different. My take-home pay is noticeably higher because of that and the lack of state income tax. Couple that with a substantially lower cost of living [1], and my dollars go a lot farther.

The financials of it isn't the end of it, though. The nightlife is better, the people are nicer, I can have a backyard, I'm not severely limiting my options by having dogs, and the weather is better (for me, but I'm used to hot). I'm significantly happier in Austin.

[1]: My 2-bedroom house that I live in by myself costs about what I was paying for my share of a 2-bedroom apartment in SF. Both required about a 10 minute commute, though I drive in Austin where I could walk in SF. It extends beyond rent, though. Everything in SF is more expensive, though nothing is quite as dramatic as the rent.
