None of them remind me of NYC or Chicago. But in terms of southern cities that feel like a "big city":

Atlanta
Dallas
Miami

I'm sure Houston does as well, but I've never been there. Austin doesn't feel like a big city to me yet, although downtown Austin is becoming competitive with the downtowns of some cities much larger than it. Charlotte also doesn't feel like a big city to me, but that city also has a large downtown and is growing rapidly.
