To me there is a difference between an "elk hunt" and an "ELK HUNT"!
I am in line for a premium limited entry elk hunt (many bonus points) and my goal is coming home with a bull of a lifetime. I would not consider using any of the OP's ammo for an "ELK HUNT" of that magnitude. I've settled on the 177g Hammer Hunters in my 28 Nosler for my eventual hunt. I want to know that if a big bull presents only a shoulder shot, I can take it with confidence.
On the other hand, I have taken spike bulls with much lighter medicine knowing I could choose my shot to fill the freezer.
That said, I'd recommend taking the ammo that's most accurate, if it fits the situation.
