1. "VIBRANCY" - i was there during UT's winter break, when most of the students were out of town, and the city was still 20x more vibrant than kansas city. downtown austin is just ridiculous in terms of nightlife. granted, most of the bars are of the frat-boy/Spring Break variety, at least on 6th street, but there are cool, more "adult" places to hang out all over downtown austin. there are probably 25 bars in a 5 block area just in the main bar district, plus the bars nearby on the perimeter of the district. they close the street at night to permit proper partying. i don't want to imagine what that scene is like when the students are in town. christ. i assume that warm weather + 50,000 college students + huge influx of moneyed young professionals = good nightlife in a city. austin has that.
2. "URBANITY/BUILT ENVIRONMENT" - austin isn't very urban. to me, the entire metro feels like an austin-sized slice of los angeles, only much less dense. most of the development is comprised of 60s-80s apartments, low-level street-facing retail, and some newer, beige, denver/seattle-style 6-10-story condo buildings. there are some very, very cool neighborhoods in austin though. the huge influx of money down there has resulted in some truly incredible (and often hideous) homes. also, near campus, lots of people have rehabbed older homes (40s bungalows -->60s ranches) to make them really cool. there are lots of "Dwell" style modern homes and rehabs. downtown austin is pretty decent in terms of built environment. it is probably the size of downtown Clayton, MO, but contains the aforementioned bar/nightlife scene that puts KC (and most cities) to shame.
here is what is important to me: austin is a great example of how a city can be awesome and vibrant without being very "urban" or pedestrian oriented. (it is definitely bike-oriented though.). the urban core of austin outside downtown is rather (dense) suburban, but it is incredibly healthy, fun, and interesting. attitude and interest in the city can go a long way - after all, there are plenty of dense, pedestrian oriented cities in america that are complete shitholes, and there are cities like austin and, say, many CA cities, that aren't very ped-friendly but blow many "dense" cities out of the water.
3. "ATTITUDE" - this is where austin just destroys KC, STL, and most cities i have been to. when you are in austin, there is this feeling in the air that austin is AWESOME!!! people who live in austin fucking LOVE austin. there is so much pride and interest in the city, unlike the naysaying attitude most have in KC. perhaps suburban austin is like KC in this regard, but i doubt it. obviously, there are bars and restaurants and attractions in the suburbs, but downtown Austin (and the Guadalupe/student ghetto area) is very clearly the "magnet" of the metro. it attracts people during the day for work, and it attracts people at night for drinking and dining.
4. "MISC" - if austin weren't so f'n hot and sunny all the time, i would consider moving there from KC in a heartbeat, despite the ugliness of its built environment. i love the progress KC is making, but it is sad to see a metro half the size of KC that is twice as vibrant, interesting, and healthy. KC seems to have a bigger/better art scene, which is cool. the austin museum of art is approximately the size of the Kemper. austin's music scene is like the KC/lawrence scene multiplied by six. austin is very progressive politically as well (or at least its residents are - i don't know anything about its municipal politics). it is a non-smoking bar city too, which is awesome. it's great to come home from the bars and not need to hook myself up to a breathing machine. there are also numerous large farmers markets and organic co-ops all over the city, making great food available to everyone. great restaurants too, although i suspect KC competes very well in this category - except for the organic/vegetarian category: austin has at least 6 veggie restaurants and KC has, like, two.
overall, austin kicks a lot of ass, especially for its size. it is definitely a west coast-y city, with an obvious texas fetish. austin makes me wish KU were in the heart of KC. sorry folks, i must say that Austin is basically superior to KC in all aspects relevant to a 25 year old male.
