As Hokages. (Not favorite, or power)
1- Minato.
He made Konoha win the 3rd war. Defeated obito and sealed Kurama. He sacrificed his own son for the village.
He helped again when he sealed Kurama again during the fight with pain. And it's stated that no fail.
2- Tsunade.
She helped greatly in the 2nd War as stated by Jman. She was the one who came up with the plan to make a medical
Ninja in each team which is very smart of her indeed. She helped to protect thousands of people during Pain's attack
and of course protecting people is more important than the houses and these stuff. She also trusted Naruto and that
helped to protect the village. Not to mention after Oro's attack it was she who made the plans for missions so the other
villages wont attack Konoha.
3- Tobirama.
He was the one who came up with the idea for the Academy, ANBU and Konoha Military Police Force. However, he is
the one who create the Edo. Therefore, he IS responsible for what happened because of this dirty jutsu, also because
of him the uchiha planned for the coup d'etat, and both of these things were stated by oro in the manga.
4- Hashirama.
Well, he crated Konoha which is obviously the most important thing to begin with. But, I listed him here because as he
stated himself
You must be registered for see links
but that might be not vary fair from me, I don't really know.
5- Hiruzen.
he protected the village from Oro, Hashi and Tobirama when they attacked it. I'm not really sure if he did something else.
and for his mistake they are too many. Maybe that's why I putted him the last one.
but that's only my opinion.
