Australia is really nice country. Australia is a very high developed country characterized by a very high rank of Human Development Index. This country is also strong in financial, and really multicultural where you can meet people around the world. The citizens are friendly and you can enjoy a freedom life.
Sweden is by far the best and most developed country I have ever experienced. It is far ahead of all European countries including the rest of the scandinavian small countries. I love Switzerland but objectively, I struggle to see any comparable country to Sweden. Sweden is the best country to live.
Germany secured its top spot for a number of reasons, its economy key among them. The country is also, as U.S. News notes in a country profile, home to low unemployment, popular around the world, known for its high-quality brands and adept at using soft power abroad. And U.S. News credits Germany's leadership for its global rise.
In conclusion Switzerland is one of the best countries to grow up in and one of the most superficially serene places, however, it is not the best. Depending on your life situation it is better to stay somewhere else. To grow up and to die it’s perfect, to truly live an interesting life some other places are better.
