Wankers gonna wank.
Specially because Sasuke intelligence stats are 3.5 and Naruto's are 3
I'm not even talking about stats or hype. Facts count.
Orochimaru:
1. Created his own dimension.
2. Developed (not learnt) tons of jutsu by himself.
3. Deciphered the Stone Tabled without Sharingan.
4. Successfully ran several hideouts while being number 1 in the Bingo Book.
5. Conducted countless medical experiments, successfully implanted Hashi DNA into others, gained immortality.
6. Is one of the most knowledgeable characters in the manga, with probably only Madara being in the same tier.
7. And many more. Hell, if we count hype, Orochimaru was a once-in-a-few-generation genious and even Hiruzen admitted inferiority to him (Databook fact).
And people dare to put Sasuke, Kakashi or Minato over him? Seriously?
