The company is in charge of maintaining the Powerstrokes. Not sure of any issues but none has left me stranded yet. Power is adequate, I don't notice any bad smoke. I'm just not sure if all the emissions control equipment are still in place on the rigs. And there are a variety of generations for the 7.3. The older ones being really bad even in the domestic market. Powerstroke.org is a good place to visit if you need to study Powerstrokes.
GM has Duramax motors (manufactured by Cummins? Not sure). And they're supposed to work well anywhere because the engine is used in a variety of vocational applications.
