Once you get OUT of the problem areas ( Hartford, Waterbury, Danbury ) you should be fine on 84....
Like stated above, seams like a waste of time to go North to NH just to go South again... especially when Binghampton is a solid hour from Scranton ..
AND taking 90-88 takes you threw Albany and Schenectady AND Binghampton..
If starting in NH, YES, Starting in Hartford ,stay on 84
via 84 - 3 hrs-11 minutes/192 miles
via 91N-90W-88W-81S -4 hrs-45 minutes/300 miles
