Surprised Mario isn't running away with this one... Lumping the platformmers in with Mario Kart/Party/Paper/Dr/Smash Bros was just too much for me to go with the others, even if I love the heck out of Zelda.
Otherwise, there's few things I get more excited for than a main installment of Super Mario and Zelda on the consoles. I wouldn't want to pick one over the other in a head to head.
