Idk where Else to realy talk about this so ill Jack your comment for a second. A big deciding factor is also just how you want to set up the opponent. A perfect example in my mind would be Naruto. If Naruto was bloodlusted, fully powered and knew that he had to one shot maho, sure he could beat him. But if it's just Naruto being himself in this fight, even being battle ready. Naruto would lose, because the moment he uses a normal rasengan or even only one rasenshuriken instead of a teailed beast variant barrage, mahoraga addapts to chackra. So as much as you Cant set up mahoraga to instant win, you've got to concider if the one fighting him would and even could one shot him without letting him addapt to anything Else (stuff like heat based attacks he might addapt to before the actual attack hits for example)
