Ok when gaara fought lee he didn't use any strategies he was just stronger and I still think lee should have won that fight. His fight with Kimimaro was great but gaara didn't win Kimimaro just died. *but I'm sorry that was way of topic.
No... THIS is off topic...
im smarter than the average bear
wow... so many smart characters...so little time... (it closes Dec 5)
Kakashi... is brilliant... I mean... he just is...
Neji, mastered things that only high leveled main branch family Hyuugas can do...
Shikamaru, is just obvious...
Naruto, like someone said before, is a dumb genious...
Yondaime... was incredible... as far as invention goes...
Gaara, is just psychopathic...
Sakura... naaah... I mean, if something were to go for chakra control, it'd be Neji...
Itachi... see Gaara...
Sasuke... Okay, at first, no... but think back... he learned fire jutsu at a very young age... so... he's got that... and he does have a few good strategies... but he lets revenge, anger, hatred and other things cloud his judgement... More so than any other character I've seen...
Sandaime... yeah, he's smart, but I don't know about "genious"
Other's not listed...
Jiraiya, similar to Naruto
Orochimaru... Psycho, yes... genious, maybe...
Tsunade and her amazing Medical Ninjutsu...
Gai and Rock Lee... could be considered genious... maybe... without that stupid jumpsuit...
*I wouldn't vote for any of them, but I'm just throwing names out there...
as far as my vote... Yondaime... He more than likely would have finished Rasengan... but died at an early age... but he was brilliant, as far as inventing Jutsu, and his ability...
