As much as I like the Wanderers, I gotta go with classic OAV Jinnai. He's just got that bloodthirsty edge that keeps his evil from becoming TOO comic. TV Jinnai is pretty much Jinnai Lite. Same great taste, but less filling!(Oh, God, I don't WANT to know what Xel is gonna make of that last line... O_o)
Ahem. Anyway, I love both Jinnai's, but OAV Jinnai just seems the better designed of the two.
