Duramax / Allison hands down. Don't run it offroad day in and day out (that is Ford country). I am assuming you are running pavement.

If you don't mind getting an older used truck, I would try to look for a ford 7.3 litre powerstroke with low milage. One of my buddies has a 2001 Powerstroke that he runs every summer towing a 33ft 8 000lb trailer. It has 320 000ish KM on it and still runs strong. He even put a chip on since it was a year old. The only things that had to be replaced, were the brakes, ball joints which was very recent and a glow plug relay. The turbo also was going just this year because of a design flaw with the turbo wheel causing the turbo to flutter. He could have probably got another 50 000KM out of it before it needed absolute replacement and without the turbo flutter that turbo proabably would have lasted about 500 000KM at least.
The turbo flutter flaw can easilly be fixed in those trucks though with an after market compressor wheel that is about $100.00.
I have heard about the power stroke navistar built 6.0 litres having everything from seized injectors to cracked heads, plugged up turbos, plugged EGrs and e.t.c. The 6.4s powerstrokes which were also built by navistar were having everything from seized turbos, leaking EGrs, terrible fuel economy, and even short block replacements. The 6.7s Power Strokes which are made in house by Ford themselves, seem to have been much more solid than the 6 and 6.4. There have been a couple of cases though where the 6.7s were dropping valves but mainly in the F 450s and up. The biggest issue they have had though, that is now fixed is that the computer programing for the tranny in the first trucks was causing the trucks to hard shift and shift into too high of a gear which did lots of tranny damage. After that, it sounds like these trucks have mainly been good news and they put out a whopping 400hp and 800ish ftlb of torque. If looking for a new or recent truck, I think I would stick with a duramax though, as their Allison trannys have been proven to be durable. Even though I am a ford guy, I have been hearing about much less problems with the Duramaxes as opposed to the navistar built 6.0 and 6.4 litre power strokes.
I had a 7.3 & loved it only MODED
Stock She was a fricken slug
Yeah, they're definitely not a speed truck when stock. When my buddy put the full chip tuning on that truck though, I would be sucked back to the seat a bit. That was when the truck was unloaded and on flat ground.
2004 chev duramax 6.6, Chipped with a diablo performance! Awesome truck!
