I also would not rule out the GM 6.0. From experience, I can tell you that the 6.2 has anemic electronic throttle response and is not very eager to downshift so it feels like a dog until you get on it. Once you get used to it, especially towing, it's a non-issue. In real-world tests, they all get the same fuel economy and you need data loggers to measure any performance difference because they are so close. Just a change in grade or test speed can change who comes out on top.
