I voted antelope simply because that's what i would do given my own level of hunting prowess.
From what I know of blacktail hunting, it really is a challenge even for those who know them and something I would believe I would need to put in a lot more time in (to be successful) than I really have.
Having been to Alaska, although I haven't seen Wyoming, I would agree that Alaska is probably much more beautiful, since I think Alaska is probably the most beautiful place on earth.
