Here are some ideas more in line with the original topic. Where we feel the most comfortable is probably what's best for us individually. Perhaps colder climates are better for endomorphs/thrifty types because it requires the metabolicsm to speed up to keep you warm. Maybe warmer climates are better for ectos because we're burning up too much energy already. I like warm because I'm very ecto, and I like dry because I have mold sensitivities. If I didn't, I'd probably like a more humid climate.
