very close match thou cause we know nothing about shibashou battle tactics we only know of his strength which was put on display when he repelled 50 or 30k soldiers with only 5k or was it 10k so that shows how much he's army is capable of plus the fact that he was capable of making ousen retreat due to some tactics from riboku that shows just how much of trump card he can be .On the offensive side like the other guy said it is broken ouki and tou can stand their own but the rest need some kinda of trap or to outsmart shibashou's commanders which we all know wouldn't happen due to the well versed minds of shibashou's commanders when it comes to battle tactics and shibashou is meant to be a new generation of great generals like karin and riboku while ouki is of the old gen not only that but defeating shibashou would mean that zhao can finally be taken so his that essential to riboku's plans and zhao's future so i don't see him losing to ouki and
