Lived there until around 2021 and visited often before the hype. It is the same as the rest of Texas, but offers employability in the technology sector. People have this notion that there's a "different vibe", but really it feels like political posturing and wanting to feel hip.
There's nothing really wrong with Austin, and it has a cool lake. But that's really it.
The problem is Austin is becoming very hostile cost of living wise to regular people (read: non 200k+ tech workers). That in turn has an effect on lifeguards and EMS.
Finally the city is good, but the city is extremely overhyped. It's very similar to Houston, San Antonio, and Dallas but for some reason gets 5x the praise. Let's be honest why: it has the most progressives and also satisfies tech workers desires to appear diverse but mostly be around other white yuppies.
