For me since the 7 Swordsmen aren't in(Damn you CC2!!!), I would have to say Utakata is the one who I really want to try out. I am not sure why but he just seems that he would be incredibly fun to play as. And his Awakening seems to be the best one out of the Tailed Beasts.
Damn CC2 for not giving me the 7 Swordsmen of the Mist in Storm 3......damn them to hell.
I was excited about him to before I saw Utakata's game play.
Utakata looks fun but while I like rangers even though two of them (Temari and Tenten) are mains of mine, I don't use them enough to be super exicted for him I dunno maybe it's the slow bubbles or something, which will bring in an intresting bait and trap stype of fighting with him for sure, but not something I'm stoked over yet, I'm sure I'll love it when it happens. He'll be used allot by me but not as much as Yagura. (Or some others.)
Yagura's my favorite Jinchuriki, and was a Mizukage to boot, and the Water Style in his Moveset looks amazing.
