@Everyone who said Kakashi:
Kakashi incorrectly analyzed Obito, unable to find out the secrets of Kamui until the second fight between them. He admitted that he didn't truly understand Kamui at first. [

Minato found out his weakness and found a counterattack able to get past Kamui, something Kakashi, Gai, Kirabi, and Naruto together could not do. [

The only real competition for Minato in analyzing situations and pure intelligence in battle is Itachi.
This was because unlike minato itachi never had
A real fight against obito. Obito even admitted
If he didn't kept his secrets he would be dead.
Clearly if Itachi was better at analyzing an
8-year long "situation", he would've find out Obito's secrets. Even Konan found the weakness of Kamui and almost defeated him. Itachi merely threatened him, and Obito used him as a tool to stimulate Sasuke.
