I think a real thunderbolt ross would have at least attempted to take out abomination and probably would have never let banner hulk out, especially since he's spent five years of his life trying to find him.
same goes with the ending, a real ross would have tranqued the hulk and not just let him jump off.
FIVE years is a long time ya know. Ross is supposed to be passionate about taking out the hulk, even overzealous. You don't let something like that slip out of your hands unless you are one sided.
Hurt also didn't do any sort of job of defending himself against blonksy, he loooked like a naughty boy standing inthe corner when questioned about it by banner. Ross doesn't get sheepish under interrogation.
Look at Elliot's, He's happy to fry both the hulk and his dad if anything goes wrong, he doesn't care and he happily nukes them both BUT he never gets that satisfaction of knowing the hulk is gone, it's a empty victory, he know he hasn't won, so he continues searching even willing to forsake his relationship with his daughter for it by tapping her stuff.
There's a scene in the desert where both the hulk and ross make eye contact. You can tell the hulk wants the bad general to leave him alone while Ross is telling the hulk he's gonna have his balls for breakfast.
Plus general organisation and military knowledge as well as respect, I do think elliot's carried it off better
