sasuke is a geniuse as well saying he is nothing to kakashi is a little farfetched
I wonder why only Kakashi and not Itachi.
He may be a genius in terms of skills, but really, his intellect seems to be lacking severely. In all love for his brother, he is pretty passionate about destroying what Itachi wanted to protect. That's one stupid thing. Another is, he blames everyone around for things he shouldn't. Getting blind in a matter of weeks also tells us something.
As for Kakashi, he is the greatest strategist we've seen in the series and recent chapters prove it. He knows his weaknesses, isn't cocky, stays calm during battles... totally different than Sasuke.
Itachi also is a genius, just like Kakashi - both in skills and intellect.
Sasuke, as I've said, is very talented, but doesn't stand out in terms of intelligence.
Takos that is not the right word to say. Overconfident, Cocky, etc... But Sasuke is smart. He absorbed Orochimaru through his Sharingan genjutsu, he found the weakness of Deidara's jutsu, Danzo got caught in his weak genjutsu making it seem that he had one eye left, and Itachi called Sasuke strong for almost killing him with Kirin, he also said had he not have the Susanoo in his arsenal. He would of lost.
Sasuke just lets his emotions get in the way, becoming so stubborn in his repeated attacks. When he concentrates and he is calm, he actually spots enemies weaknesses very well and comes up with creative battle plans. Itachi is no doubt better than him, because he keeps his cool. Sasuke is probably a bit better than Kakashi in planning or on par. A genius is not given a title just for being a show off. Itachi, Sasuke, Kakashi, Shikamaru and Neji are all geniuses. Being a genius is not determined by your strength only it's determined by your ability to solve problems and be creative in more ways than one.
Well, in Part I and part of Part II he was intelligent. It's only later that he started acting really dumb.
Sasuke is probably a bit better than Kakashi in planning or on par.
I absolutely don't agree with this statement. Sasuke would have never come up with such plans as Kakashi's, which are shown even in most recent chapters.
Being a genius is not determined by your strength only it's determined by your ability to solve problems and be creative in more ways than one.
I agree with it, but in Naruto term "genius" has been used about other things than intellect. Sasuke was called genius because he was very talented. Lee was called a genius of hard work, which has nothing to do with intellect or even talent.
Sasuke was never stated to be as intelligent as Kakashi or Itachi.
