I’m not sure I really have a favourite. Every country has good and bad. There are some parts of the USA (ex. Colorado, Washington) that I really like. But also the USA has its own issues that we all know about. France is beautiful but there can be civil unrest, taxes are high, etc. I spent some time in Singapore and it’s very safe, clean, great food, but it’s also stale and far from a lot of places. Culture comes into play a lot. I can recognize that somewhere is a great place to live but it’s not for me. I didn’t grow up there, I don’t speak the language, etc. In Europe I feel most “at home” in the Netherlands.

Different things matter to different people. So saying things like “this country is #2” are meaningless. Countries I personally would rank above Canada: USA, Netherlands, Norway, Australia, New Zealand.
