Okay, to kick-off this: I 'm in favour of Shanghai, because there are more pretty girls AND beautiful women. :) I'm currently on another biz-trip in Shanghai, and my observation tells me the story everywhere. On the street, in the office, in the clubs, you name it. Women here (seem to) have better sense for style and attitude. Of course I know appearences are usually deceptive, particularly in China. :)
So, which city is your favorite, if you have to pick between the two? And primarily why?
