Poor emissions when stock; however tuned, a 6.4 will be the best thing that ever happened to you (power and mpgs). PM me, and I will fill you in on my opinions...i have owned a 6.0 too, and I have worked on all the trucks you have listed. All depends on Personal opinion, what you use the truck for, what you expect out of performance, interior/comfort, exterior look, and modification friendly. Clearly warranty is not an issue for you, so my first advise is start with an oasis report on each one of those trucks and test drive them all over night. If they don't wanna let you take the truck overnight to test drive, consider that one out of the pot. You are on a ford 6.4 forum...so obviously everyone's opinions are heavily biased. Go to a cummins forum or a GM forum and they will all differ in opinion...hell before I bought my 6.4, I had a 6.0 and badmouthed the 6.4's. Now, i swear by them, and have made quite a bit of money at the drag strip off of the 6.4.
It's all a matter of preference and opinion. best news is you're in the right field (diesels). Keep us posted on how it goes!
