After the engine in our '09 V10 6.8L F250 'sploded 3 days ago, we ended up with a new-to-us replacement '12 GMC 2500HD that we were able to find on very short notice. The V10 6.8L was rated 362HP w...

Horsepower is the measure of work that an engine can do. With both trucks having about the same horsepower, they both will get to the top of the mountain in the same time. Those that won't run an engine at the RPM necessary to develop the required power will complain and comment on lack of torque. High torque engines will actually work bearings, pistons, clutches and gear teeth harder than a lower torque engine running faster.
So diesels should be avoided by this logic?
Since the V10 has two more pistons and an extra main bearing the stress is probably handled well. Actually, both engines have excellent reputations, just different ways of getting there. I do sympathize with finding high RPM objectionable but that depends on how well the engine's sounds are contained. With each new generation of engine that I have purchased I have noticed a drop in objectionable sounds and am willing to run more RPM.
I actually have a diesel, but thinking torque is a big deal and that there is no downside is not true.
