Wow, surprise so many write off YYH like this. They are casual mountain busters by feats.
Anyway, not sure who number 8 is but for sure possibly loses to ( (Naruto) though IMO I feel Wankchigo, I mean Ichigo is a even fight for EoS Yusuke. Both are simply Mountain Busters and speed wise if we scale Yusuke to Hiei, as well that time Yusuke speed blitz dozen A and S class demons in one move, thats insane fast.
The issue is power scaling, as by on screen feats mountain busting is the limit in power, and speed wise much faster than lightning (early sagas was arguably lightning timing). Yet in "statement' we get consistent statements of power to bust countries and ruin the planet by accident by just fighting on it.
So by feats I feel Yusuke can scale fine to anyone minus BM Naruto, but by statements he surpasses them all.
