All have really good voices, but Ryeowook IMO is the best. He has great technique and he has a good ear so he rarely sounds off-key. He also sounds pretty much the same live. Plus, his voice is so beautiful :) Yesung is probably 2nd. He is really great at putting emotion into his voice, and his voice is nice and husky and deep. He just isn't as stable live and he can sound breathless. Kyuhyun is also good, but his voice doesn't stand out as much compared to Ryeowook and Yesung. His range doesn't seem as wide either. But they're all great.
come on. . . we all know it kyu!! his voice is like an angel's. . . thou i do have to give yesung n wookie سہارا cuz i love their voices too n wookie is super kawaii
Kyuhyun! it's not سوال about it .. his voice is so nice and handsome face .. I love it ... but, Yesung and Ryeowook too good ... I love all three of them!
