Well I didn't say they have harder or easier choices, I said there is a difference in the amount of choices. A very large one.
And I really disagree with your stating that once control gets ahead they win on auto-pilot. In control matches, it is much harder to tell who is ahead most of the time and more importantly, how far ahead they are. Even against more aggressive decks, it isn't like you can play on auto-pilot once you get some semblance of board control. A good midrange/combo player knows ahead of time when they are going to lose control and they've prepared for a way to get back into the game even if it isn't directly in their hand.
To reiterate, I didn't say hunter has easier choices, but far far less choices during the course of a single game. Sometimes the games are so short and straightforward there is no real choice involved. You either make the obvious play or lose. And every once in a while, perhaps once or twice a game, you trade instead of hitting face. Measure those few real choices, hell - even add in the choices the opponent had to make, against a match that lasts even an additional 3 turns, it is no contest.
