I have also noticed that one kind of person will normally go for the city that suit his/her personality (due to experience and the way they have been brought up), for example a person brought-up in new-york will most possibly won't like atlanta and vice-versa. the reason being NY guy is used to speed, he just cant take anything slower, if the train is scheduled at 7.13am then he has to be on platform on time, while a guy in atlanta will get anxiety if he goes to NY and have to rush his life with everyone else.
City with laid back attitude also tells you that people over there dont care for money but that doesn't mean people dont make enough money (in fact they enjoy money at the fullest), on the other side people from the city of speedy lifestyle always feel like they dont have enough money even though they make good money, this is partly due to the cost of living and the culture where everyone wants to make more money.
Also people from laid back city are not in-secured the way people are from busy places like NY, London, Bombay, Tokyo etc. People from laid back city dont worry about what will happen tomorrow, but people from city like NY and Bombay are constantly worrying about tomorrow, it drives them crazy if they are not planning their life/career in advance.
