I can't speak about Austin, TX, but here in NYC a number of aesthetically pleasing buildings have been built in last, say, 30 years. Even asymmetric ones, like <https://en.wikipedia.org/wiki/8_Spruce_Street>, look great; I'm saying so as someone who used to see downtown Manhattan every day during commute. (One thing I miss after switching to WFH.)
Yeah, that's ... weird. But then again (in my opinion) all skyscrapers look like crap and only become "iconic" by being there for a long time and people get used to them.
I don't think that the Art Deco style skyscrapers look like crap. I quite enjoy them. I think most modern sky scrapers look like crap because they're all done in a modern style with no decoration. Other styles never really got a chance to express themselves since everything was taken over by the modernist look.
