I dont know on what ground Nepal is the best. If you are talking about the natural beauty than probably Switzerland or Newzealand are the best. If you are talking about hydroelectricity potential Brazil is the best. If you are talking Nepal being the best in terms or crime then alas sudan or Iraq are far ahead of us. If you think Nepal is the best in terms of being poor than there is ethiopia which is more poor than us. Alas we cannot even boast mount everest being the tallest peak in the world when Mauna Kea in Hawaii is taller than everest (measured from the bottom on the sea bed), it's over 33,000 ft tall or 10,000 meter
