I wish I had driven the Chubby for comparison, but I did not like the looks enough to even try it. I did drive a loaded F-250, and there was no comparison to the Dodge. Drivability was so far beyond the Furd that it was not even fair. I have friends with Chuby's, the one thing that sticks out is that soft ride, too squishy for me.
Dodge: Beauty eh, number one diesel engine, smooth auto trans, very nice finish without orange peel, very nice interior, lots of goodies in the Laramie package.
Furd: Had 3 Lightnings, the best at what they are made for, factory speed in a truck; but thier HD is slooooow, and a boat. Interior is cheap and old.
Chuby: But azz fugly, soft as an old sofa.
But hey, they are all American trucks, so try'em all. The opinions above are based on my own meeger experiences.
