Don't get caught up in rankings! Just go to whatever city you want to live in if you want to be in D.C. then go to school there and if you want to live in New Hampshire go to FP. If you really don't care where you live then Franklin Pierce would probably be the better choice.
Franklin Pierce is the only school in it's state so it might be easier to get started there, but there is not much in New Hampshire. I did interact with the staff a lot, because I got admitted and it seemed like a reputable school and they have a really high bar passage rate, which is definitely an important consideration. However, law school is a personal choice and any ABA school will teach you the same things, none of them are out to ruin your life or anything and if you put the work in at any ABA school it will work out.
