Bleach any day. I mean, everything about Bleach was awesome, from Ichigo to the 12 Court Guard Captians, to the enemies they faced. That and Ichigo is the only character I've really been able to relate to. Always trying to find a better way to solve problems, always trying to not resort to violence, trying to always make people see and think about things in a better way.
Always trying to suppress a darker self that would rather rip into everyone and everything, always being haunted, that little voice within yourself. Not knowing if or when it might just take over.
Still there are plenty others anime that came pretty damn close. Collectively these guys would be 2nd.
And these would take 3rd.
