They're all the best, because each of them is fit in their oun Way of singing & acting. They are all great & Unique performers. I will vote all of them as the best!!! But in my First choice, the leader Leeteuk is #1, He's the very Best!!!!!
Kyuhyun for sure. He's so multi-talented! He can dance, play various instruments, is drop dead gorgeous and sings like a choir of angels. He's my bias. And I feel like he doesn't get enough praise for being so amazing!
