No specific rules here. All I ask is that you provide valid explanations as to why you believe one or the other would pwn their opponent. Manga explanations have slight advantage over anime related ones. (Manga is cannon, anime is filler.) 'Because I said so' is fucking stupid and will not be admitted as a valid argument.
