I wouldn't be surprised to find there is no advantage to either route. You might want to use the hill you mentioned by taking that route in one direction only, to give you a downhill advantage. The shorter route is fewer miles traveled, but the longer route may yield better MPG. Sometimes you just can't win...
The vehicle would be at operating temp. Maybe I forgot to mention the commute home involves about 9 miles of freeway travel before I get to the point where I could take the 2 ways.
