Ok, has anyone else stayed this long reading this discussion because of the fight?... just me? hehe xd I won't say which one I agree with, I don't want my head bitten off, let's just say I think one them was right, except in one thing, everyone has a right to like or dislike whatever they please.
Anyway, to answer the question, from:
Tsunade- Hokage (I'm counting
her, 'cause
I prefer her over Danzo)
Gaara - Kazekage
Mei - Mizukage
A - Raikage
Onoki - Tsuchikage
I have to choose Gaara, why? Because he has awesome powers, was powerful enough to become kage, and protect his whole village against Deidara. And because, even if it isn't really provable that he is the strongest, the other kages are at their peak of their power, he is only 16 or so, he will continue to improve, and get even stronger. You don't get to be the youngest Kage just because your cute and had a sad story (even if he is cute <3 and has a sad story

) and that means something.
