I disagree completely, also with everyone else. It is absolutely clear that both moves win. Neither move can be considered superior, since winning is the object of the game. It does not matter that one mate is shorter than the other. In the same way that a 3 move checkmate and a 12 move checkmate both win, either dominating gain of material wins. If the delaying move caused a loophole that allowed the opponent to escape it would be different. One move cannot be said to be better than the other, from a game theoretical standpoint.
