Australia, I lived there for five months, I can tell for everyone some reasons:
The most important is quality and style life, I lived in Brisbane for two months and Gold Coast more two, very quiet city, almost there is no traficc cars, public transport working very well, all people respect you( when I said it, so many aspects that I could stay hours listing here), all rule are respected , The climate is fucking amazing, of course that depend the city. There are many beautiful, clean and organized beach's.
I would like to spend some months in switzerland and USA!!!!
