There is no single answer.  The United States of America has the largest economy of any country, but Qatar has the highest GDP per capita.  Finland, on the other hand, is the happiest country in the world.  Russia is the largest country by landmass.  Many consider New Zealand to be the most beautiful country.  Which country is best depends on what you are looking for.
