Really, it depends on more factors than that.
Unless fuel economy were your main concern, I would go with the Ford. The GM trucks are a bit crude in both fit/finish and technology.
The Fords are much nicer overall.
The one thing I would point out is that even though the GM trucks get excellent fuel economy, under load the Ford evens the gap and also is less frustrating to drive. The Ford develops a lot of power early in the power band while you have to work the GM trucks a bit more.
I found the Ford pretty much a quicker pickup because of that, though the fuel economy was bad because of that. However, under load, with all of that power at low revs, you should be able to haul/tow without having to really mash the pedal.
