Kaguya killed him and ate the fruit for herself, right? So why is it that he's still strong enough to stomp on Naruto & Sasuke? How can Isshiki be around Kaguya's level(or higher) despite not eating the fruit? How'd she beat him in this case? He's restricted by his host body too. Are Naruto and Sasuke just that weak or is Isshiki truly powerful?
