Konoha:
Senju Tobirama.
An inventor with creating jutsus like FTG, Edo Tensei, Kage Bunshin.
Sacraficed himself to save his team.
And he has style

.
Kirikagure:
Hozuki Gengetsu.
Super funny guy. Seems to have a great heart as well.
Cool jutsus. Cool looks.
Sunagakure:
Gaara.
We know very little about the personalities of the other ones except Gaara's father and
I dont only choose by looks, so Kazekage 1 up to 3 are not considered by me.
I consider Gaara a great person. Really mature at his young age.
Kumogakure:
I dont know much about the first 2 Raikages. The second Raikage was planning an alliance with Tobirama, so that tells something about his personality I guess. Wanting to negotiate and such.
I like Darui the best out of all the Raikages. Seems like a forgiving person, who apologizes when he is wrong and such. I can appreciate that. I like his attitude.
He also is less of a taijutsu wrestling maniac like the Raikage before him.
I like his Stormrelease, water, lightning and sword fighting style more.
Iwakagure:
Muu by far. Great character who quite changed in personality as Edo tensei (from someone who wanted to take advantage of the spoils of war after the war and the alliance is over, to one who wanted to continue the alliance and peace after the war was over. Having learned from the changes that took place in Onoki.
Muu looks awesome as well. Cool abilities.
