I like Link on a much deeper level because I prefer the Zelda series and have played many more of the games, but Mario is more accessible and his games are quite light and happy. They're both super-awesome, but I like playing the Zelda games better, so I guess I'll have to go with Dolentrean, because I'm an indecisive twit. I would never want to see Link take Mario's place as Nintendo Mascot.
