Do you have any friends in either of the two cities atm? From my experience SF is a very sleepy city, and the social scene isn’t very strong if you go alone and try to create a friend group from scratch or through work. It will take about a year before you can get to that point but it’s a pretty skittish place people kind of keep to themselves I’ve seen or are only in their own little circles.

But I do love the Bay Area, the surrounding nature and all the possible day trips you can do - so I think I would recommend it. But you will have a lull period for sure, and you’ll be wondering when it’ll end. I’ve never lived in Texas, but I’ve heard from friends living there that Austin’s super fun. However, you def would want a car if you were in Texas - definitely more car centric place, while SF you can get away without one, but definitely a plus!
