The 6.7L is a winner so far, it doesn't have any real chronic problems, and makes a lot of power and gets reasonably good fuel economy for what it is.

The 7.3L would be my 2nd pic, it's basically indestructible, but compared to today's diesels, it's down on power in stock trim.

The 6.4L corrected a lot of the issues with the 6.0L but it was saddled with new-at-the-time emissions gear which killed it's fuel economy. It wasn't much more fuel efficient than the gas V8 and V10.

There was no powerstroke 6.3L

The 6.0L was a hot mess, especially the earlier variants, the later ones (2005-2007) were better, but the engine had design flaws that should've been caught in before it went into production. Once you get them bulletproofed however, they are pretty reliable.
