I'd say yes efficiency since Diesel engines are also about twice as efficient as gasoline engines.

But also diesel engines have so much more torque you don't have to wring the piss out of the engine to get moving. With diesel you get most torque at 1500 rpm but for a gasoline engine you're revving it to 5000 rpm to get any torque, and burning more fuel.

Less rpm less engine wear too but most diesel engines are built very well to handle the compression ignition.

Diesel are also better in wet weather compared to gasoline engines although gas engines are better than the used to be.

I think people in the US still imagine a diesel with visible exhaust spewing out soot something from 30 years ago.
