Best places to live

What are your top 5 choices for places to live, and why? They don’t necessarily have to be places you’ve personally lived in, but at least explain your reasoning.

Travel vs immigration:

Travel is a temporary experience for purpose of leisure/tourism/exploration/trade that is characterized by mobile experience. Typical traveler "I went to the nearby beach(*snap*) and got 3 seashells(*snap*) then i went sightseeing at the local safari(*snap*), here is my Instagram experience"

Immigration is characterized by one-way travel to somewhere and staying there for specific professional/economic/educational/cultural/etc goals: its a static experience. Typical immigrant "I want to live in Japan. Why can't i get permanent residence status?"
