If I were buying a half ton to tow with, I'd almost certainly end up in a 3.5 Ecoboost. The low end grunt can't be beat in that class and the 36 gallon tank is a great feature, as are the towing mirrors. I've got a friend who's had a couple of them and they perform really well with the caveat that they aren't very fuel efficient, but that's where the 36 gallon tank comes into play.
This would be my choice as well. The Ecoboost is a great tower. If you get the max tow, you get the best mirrors available, the 3.73 gears, the best IBC available, and an extra 500 lbs of payload. The Eco will get good mileage not towing, so great grocery getter for the Mrs. too.
Compare, buy what you like!
