Pre DEF Diesels - which is better Cummins or Dramax?

I got this.

In 06 I needed a new truck. I looked at both the Dodge and the Chevy.

There is a bowtie in my garage. Why? The ONLY reason was the Cheby had a 6 speed and the Goat had a 4 speed.

I have rode enough in a Dodge with a 4 speed to know I didn't really like the auto 4 speed deal. They are alright but I would want a 5 or 6 speed way better.

(Oh, on edit I needed a true 4 door and I think Dodge at that time only came out with a 2 and a half door.) :B
