Disregarding the human factor......
I've travelled all over the U.S.- minus Alaska.
With 16+ climate zones, I think it's all GOD'S Country!
There's not one area I didn't fall in love with.
As for living wherever - I do know I, personally, need to live by the coast, any coast.
My second favorite was S. Dakota Badlands (although not in winter. LOL!) I found them mystical and erie and gorgeous!
