I think there are 2 important differences between a turbo gas engine (like a 3.5L EcoBoost) and a turbo diesel (like a 6.7L Powerstroke).
The turbo gasser is made for fuel efficiency with no power compromise. Think of the advertisements for EcoBoost - heck, even the names tell a tale. The ads brag of the mpgs.
The turbo diesel is made to tow and haul and is built, designed, and tested accordingly. The diesel also has much higher cylinder pressures and is built to withstand those pressures which inherently makes it more durable (when built correctly). The ads here are all towing/hauling ratings bragging rights and tq numbers.
