Alright, our first discussion will entertain a fight between Shunsui and Tousen.

We don't know much about Tousens shikai ability "cry" but it seems it knocks the opponent unconscious. Im not sure if this would effect Shunsui; however, if it did there wouldn't be much of a fight. Other than cry, his shikai is nothing Shunsui couldn't handel prior to even releasing shikai.

I think Tousens bankai on the other hand could make quick work of almost anyone. But I have to take into consideration Shunsuis experience as one of the older captains. And his shikai abilities and "rules."

Darkness wouldn't negate his ability to use shikai, or his shikais rules: "The Zanpakutō makes the rules, and anyone who steps within the boundaries of its spiritual energy is forced to play by those rules." Meaning if he were to use the technique Irooni, him not being able to see, smell, or hear Tousen wouldn't matter. As Tousen is subjected to his game, and calling a color would reveal his position.

His speed would also be superior to Tousens, which I don't think I need to elborate on. My vote goes to Shunsui.
