I moved to Austin in 2012 and left in 2020. What was great back then was that salaries were almost comparable but the COL was so much lower. Until 2016 or so, Austin had the best salary to COL ratio of tech towns in the country. But that all changed when the Californians started showing up en masse.
Austin was never truly going to compete with SF on its perks, but it was a cool town that allowed people to live comfortably.
