These are my two favorite safeties (these along with Maryland were my 3 safeties) and I am having trouble deciding which is best. If there are any current UNH/UVM students out there, I would love your input!
Strong engineering/science program--do you feel that UNH/UVM has this?
Sizable surrounding city environment (so I can escape campus :P)
General campus niceties (is housing better at UNH? How's the food? How pretty is it? Et cetera)
I've been admitted to the Honors College at both schools so you can factor that in as well.
