Aspertia IS beautiful - yes (and it does win over Nuvema in that way). But it feels weird how everything is thrown at you. Boom, here's a gym. Boom, here's a Pokemon centre with a Pokemon mart built in. AND IF YOU GET BORED, HERE'S SOME MORE HOUSES FOR YOU TO ENJOY.
Whereas Nuvema is homely - you feel like you're coming home to your little old town after a long journey... and back to where you took your first steps. It's a nice feeling. However, on the other hand... it's boring as hell. It's just like any other town. :c
