If your going to use this bike as a commuter, your going to want to mount racks and fenders and lights. All of the bikes you hyave riden would make good commuters. I have riden most of the bikes you have looked at, any of them will work. Just pick the one you like the best, yea I know its not easy. A trike would work well if your going year round, but in the $1400 the only one I can think of is the EZ-3. Unless you find a deal on a used trike.
"When the spirits are low, when the day appears dark, when work becomes monotonous, when hope hardly seems worth having, just mount a bicycle and go out for a spin down the road, without thought on anything but the ride you are taking." - Arthur Conan Doyle
