i wonder

Ni hao fellow forum members. can i ask tai doesnt like bleach so he went straight to naruto for this answer.
if gai sensei and rock lee fought ichigo and hmmm captain isan *i dont know if i spelled that right*
both team went to the extreme..gai and lee opened all 8 gates and ichgo and isan opened up bankai who would win that fight?
i said bankai at first but then i looked at it fairly cause i liked bleach more than naruto, but the gates seem way more powerful than bankai

it would be an even match, cause the flash step is just as fast as gai and lee and ichigo can take damage. but then ichigo would win because gai and lee would die after and they can probably last 5 min at the most.
