I would probably pick Twilight Princess Link not because of Link himself, who had something of a throwback design to what Ocarina of Time Adult Link had after Wind Waker gave the series an unexpected chance of appearance. What sells me about the Link of 2006 is more the environment around him, especially at the onset of the adventure. His role in Ordon, the relationships he has with each person in the village, notably Ilia and Colin, and how these relationships spur his journey along gave a sense of weight to him. This weight is nothing new, as we have seen similar senses of weight with Wind Waker and so forth with Link and his sister Aryll. Nevertheless, for whatever reason, Twilight Princess's sense of weight and motivation for the character of Link stands out from my perspective.
