without kyoka suigetsu??? watch Episode 297, even Isshin pushed him to his limit....without kyoka suigetsu, Aizen would have died quite earlier in the fight.....

He might have won if he had used kyoka suigetsu alongside hogyoku and his intellect...but he wasn't even thinking much about the battle so he lost.....
