I have lived in both cities and was born in New York but for sheer internationalism, nothing beats London and I don't think any city ever will. Even my Parisien friends prefer London as a place to live than Paris. As for Dubai, Beijing and Hong Kong, no they are too small. Well, okay Beijing isn't too small but a world center? Nah. Its a big ugly polluted city and doesn't have a tenth of the attractions of London or New York. Shanghai is much more interesting than Beijing.

Just call me Tigasin. That's what I'm talking about
