I like all three of Tao trio, functionally, design-wise and for what they symbolize, but this one here will always be my favorite of the three. I am also glad that I picked Pokemon Black for Reshiram, because then it means N uses Zekrom instead, and I think that dragon fits him better since Zekrom represents ideals. N believes with all his heart that what he is doing is just and will make the world a better place for pokemon, so he has strong ideals, but he doesn't know the secret of what Ghetsis really was trying to do, and you have to help enlighten him. Since Reshiram is the dragon that stands for truth, it's more accurate that it's the player's dragon.
