Vermont can be a great place but it's not for everyone. The towns you mention are in northern Vermont which is colder, snowier, and has longer winters. We have far fewer sunny days than Arizona--last year only 81!
I could be wrong about this and don't want to offend anyone
but my impression is that those towns have less going on culturally than, say, Burlington or Brattleboro. If you like winter sports, you'll like Vermont. If you want the arts, you can find them but your choices will be fewer.
I expect the cost of living is different than AZ but not necessarily less. Housing is expensive here relative to wages--not San Francisco or Manhattan expensive, but still hard on most folks. Heating can eat up a lot of your money. You have to have a reliable car here, and depending on where you live you may need 4 wheel drive.
