For where you are going, RT90 to RT88 it is a little longer but the drive is better. You don't have to deal with Hartford or Danbury. Albany is easier than either of them. Once you get to Binghamton, you have a choice. RT17 to Rt15 or RT81 to RT80 or even RT17 to RT 220 to RT180 . RT81 to RT80 is faster but you have to deal with Scranton. It depends on how time constrained you are and how much you like driving through places like Danbury and Hartford. Your route is the fastest but the biggest PITA too. How big depends on traffic and accidents.
