My opinion based on your criteria, probably the Accord but only because the 2010 Accord is basically unchanged from the 2008 model which has an established very good reliability record. The 2010 Taurus is a new design although the previous Taurus (2008-2009) also had a very good reliability record so this one will probably also do well, but that is not certain.
Beyond that there is really not much to choose from other than your personal taste and the price you can negotiate for the car equipped as you want it.
