Put a supercharger on the gas rig at 10K ft, NOW compare said rig to a turbo diesel. If the NA gas rig will pull with a TD at sealevel, but not at 10K, with supercharger it will now pull with the td, as BOTH now have forced air induction. Some of the older diesels like the GM 6.2, Navistars idi 6.9/7.3 to name a couple of them, did no better at elevation than a gas rig did. IF one is going to compare fuel style motors, make sure BOTH have the same advantage, or disadvantage. Otherwise, yes, one will do better in a given circumstance.
By the way, see which rig will pull a 30% grade at GCWR, a GM dmax, or a GM 6.0 gas with either 3.73 or 4.10 gears with the 6l80e.........answer just might surprise you!
