The good thing about commuting from Newtown is that you have the choice of whether to take the Merritt or the 84 to 684 route. I used to commute to Westchester, and sometimes varied it just for a change of scenery! It really depends on the hour you leave your house, and weather and accidents play a big part. I don't believe that one is always better than the other. I grew up in Westchester County, but moved to Bethel and then Newtown 16 years ago, so I know the areas and the driving times very well.
