Do you know where you'll be living yet? And have your ever driven in snow? In general - the further north you live, the more you'll need 4wd or awd. Further south you can get by with front wheel drive or rear wheel drive if you have snow tires if you know how to drive in snow and ice. If you're new to snow driving - go with Awd/ 4wd.
As for NH- it was a culture shock for me when I moved here 30+ years ago from a deep blue state. Not the fact that it is a purple state - but that as a battle ground state with the first in the nation primary - campaigning never stops- constant visits, TV ads and debate with one of the highest voter turnouts and a knowledgeable population. Lastly - despite the reputation, you'll find granite staters very welcoming.
Good luck
