I didn't say 'no diff'. I just said he will beat 'easily'
Zoro: hardening, ryou, adCoC,
Kaku: just hardening or maybe ryou.
Zoro: 3 potent swords
Kaku: fodder sword or sword that is not comparable to Zoro.
Kaku awakened?
if not, how much stronger he will be than he was in time skip? at best it is like how much g2 and g3 Luffy with basic armament.
Of course, it is just an opinion and it can change if Kaku also shows awakening like Lucci.
