I feel a lot of what sgnguy is saying as far as his criticisms of asian cities. These kind of deep problems and also all the inconveniences can weigh on you. At the same time, as AllPage said, it is a matter of personal taste and of priorities.
For example, I for one totally despise central and western Canada (anglo Canada) as the most culturally barren, socially cold, spiritless, stingy, and generally boring places. I have been (particularly Vancouver). People there may have more freedom, but it seems to me that they do nothing with it. In fact, people immigrate there from all over the world, every language and background is represented. But they seem to just kind of leave it all behind when they immigrate, trading it in for exciting activities such as shopping, aerobics, watching tv and walking their dogs.
More than that I found communication in Canada hard to navigate, kind of passive aggressive, like in some parts of Asia. Sorry, to be so blunt but it just goes to show that "one man's treasure..." etc
That said, I am sure that if you fell down on the street in any Canadian city, people would help you without a second thought.
