I doubt I'll ever shoot another doe pronghorn. I can get 2 buck tags every year and IME, the bucks aren't any different as far as table fare.
I agree with others that pronghorn is very good eating.
As to the wild sheep (dall, desert, Rocky Mountain), while edible, isn't nearly as good as elk, deer (of any species), moose, musk ox, pronghorn, oryx, etc.
