Chevy has never made a good diesel.
The super-heavy duty Ford's, I think the F-550's or some shit uses a Cummins motor. But they don't tell their average consumers that.
Honestly though, you could go with the Ford or the Dodge. The real differences that you will notice are going to be the truck surrounding the motor. I personally love Dodge trucks, I've been around them my whole life. After looking at current truck prices, I think my next fullsize is going to be a Ram. That's my personal opinion, and such should be taken at face value. To my knowledge, both Ford and Dodge use a solid front axle, which means that even though it's more heavy duty, the ride and handling is far from good, especially considering what you are used to driving.
The only problem I know of with the Dodge's are the auto trannies. I highly recommend, if you are to go that route, to get a 6 speed. You will not be disapointed. OTOH, they are highly moddable trucks, responding VERY well to boost and extra fuel. I have known several people to own these trucks, and they were always very pleased with them.
As for the Ford - I just don't know. I personally have never known anyone that has owned one, so I have no idea what their issues may be.
So long as you avoid the Duramax, I think you'll be alright. I suggest finding out more info on the Ford before making a decision, but either way I think you'll do alright.
