When the Ford dominate clan talks trash about the rest I have ZERO PITTY?? quietly these threads have emerged across the WWW over the years. Lawnsite has been drinking the Ford "Kool Aide" for WAYYY to long. The 7.3L vs 6.0L debate is never ending Many would ride the Ford brand loyalty bus off the bridge if only to save their own arse; which is insane. Ford & International are suing each other over who should be responsible for excessive warranty claims, that alone has drove owners away from Ford.
Here's some salt for the wound

6.0 main flaw is weak head gaskets, easy fix with APR head studs that will solve many of the issues. Some folks were smarter, and invest in the APR head studs right out of the box
Aftermarket intercooler solves the turbo issues
EGR delete is "illegal":sleeping:, but is the last weak link
The 6.0 will then lay down some reliable neck snapping torque
With the most trucks on the road Ford should have it right, but that's always been the excuse for their problems.
