Considering that we don't get to ever meet Kiganjo, there's no way he is gonna win this.

Hmm... First off, Kido Corps Commander =/= captain. I don't mind him being in the polls, cause I'll vote for him, but he's not technically a 'captain'. He wasn't technically one of the 13 during the Turn Back the Pendulum arc, anyways. He may have been a captain before that, who knows? (doubt it) He might even have doubled as the tenth squad captain, but HIGHLY doubt that.
All that aside, despite the fact that Tessai is often nondescript, my love for the kido corps has placed him up there in one of the most interesting characters in Bleach (in my head XD)

Tessai is okay, I guess...
