Advantage of a windowless window seat is still ability to rest head at an angle against the wall. I can't sleep when I'm forced to sit straight up, I tend to fall-forward and then snap awake and catch myself. Being able to put my head against something is the difference between sleeping like a baby on the flight and being awake from coast to coast.
