Get what you like the most. Engine wise. Can't beat the Cummins. Thats what I ended up getting. Do your own research. You will get some weird opinions from people spouted as fact. I have never seen a stock duramax run a sub 11 second 1/4 mile or a 12 13 or 14 for that matter. But I have seen modded dodges and Fords do it.

In reality they are all pretty decent rigs. Some just do certain things better than others.
