He's probably not even in my top 50.
Seriously, the guy is fun and all (used to be anyway) but I like him for the same reason I used to like Hidan- the guy is a f*cking nut and he loves it. That's entertaining to watch, it's nothing substantial or complex but it's viscerally fun. Madara has more flaws than positive traits imo, can't call myself a huge fan.
