I like Tsunade and Sakura to ´couse* Tsunade is very simular to my mun* and Sakura is very simular to me. I mean in the name of moodchanging. But if the question would have been who´s the strongest then I would*have to say Naruto for sure.
Itachi, because I find him the easiest to use and you don't have to go head to you enemy. You can use your "special" up attack. which is helpful when defeating a character when he is running away.** **
