I did like Sasuke quite a bit until just after Itachi. He was pretty cool until the spiral into insanity. When he was like "Time to kill Danzo because of what he did to my family" I was like "Cool makes sense. Go for it bro." Then he's like "ALL OF KONOHA MUST DIE".... Really guy? REALLY?
I'm currently into Suigetsu quite a bit. He's shown to be quite powerful when facing Killer Bee and taking out State 1.5 Jugo pretty quick. His dream is still better than like everyones combined.
