"I have shot all 3 rifles from various field postions not just off the bench...at this time I tend to shoot the Creedmoor more accurately...feel more comfortable shooting it too!!"
I'd say that's your answer then.
In hunting big game, accuracy is 95% the function of the shooter and 5% the function of the rifle and the ammo.
Use the one you use the best. As long as you have a bullet that will expand and still go through, it doesn't matter as much what rifle you use, as it does how well you use it.
