Ironically Luffy has been KO'd twice while Zoro didn't actually lose consciousness yet for certain.
Even if you say he did after the Ragnorak, it would be 1 to Luffy's 2.
zoro never took any attack directly... the named attack from big mom and Jairo almost killed him
And thunder vagus knocked him out up until danio bandaged him
also the main focus of the emperors the whole fight was luffy
No supernova is a top tier yet... even after this arc they will be in betweeners, cause from what we have seen to be called a top tier is to be able to give another top tier high to extreme difficulty
kaido current strongest pirate has fought 14 people and still able to k.o luffy just shows you how monstrous the emperors are and there are only 4
With one of them being a one hand no df human
