I'd have to say Tai. He's the most classic, and made an impression on me. And in my opinion, he has the coolest goggle-head digimon. So that helps too. But Takato's a close second! he reminds me alot of one of my really great friends Dakota. Similar name, same haircut, same attitude (sorta) and yeah. And He likes guilmon alot too.
But, Tai's best in my opinion.
