Have to agree w/ other commenter, there's actually a pretty surprising overlap in personality types between the two places. Maybe Austin skews a little younger (both biologically and socially).
However... Texas is for materialists, hands down. You don't go there for natural splendor or the climate. The beach is a turd, and you're surrounded by 500 miles of polarized right wing fundamentalists in every direction. But it's centrally located! Which means you will be flying/renting a car to leave town, period.
California is for people who value quality of life, and are willing to pay every penny they have now and forever, to approach it, to the point that they have no quality.
After these and other living arrangements, I'm done with population centers. Give me a rail connected village please.
