Eh, I am none these. A selection from different cuisines far surpasses any individual cuisine. Having said that, having the US so close to the top is both understandable (the rest of the world is trending more towards obesity) and a bit depressing. I think a lot of it comes down to taste. For instance, traditionally I think a lot of Asian cuisine is more complex than say Mediterranean, simply because of the wealth of ingredients on offer. The perception thing about say the sophistication of French cuisine, is mostly just that, a cultural story that has little basis in fact.
Like any other cuisine, Indian food can be amazing or crap. But then so can Italian, French, Chinese, etc. As for Chinese, I would only rate it highly based on what I ate when I went to China. Outside of China, I have rarely had anything particularly good.
