Gear 5th's equal couldn't even handle base 2 swords Zoro .
Gear 5th vs Lucci :
clashing equally , and calling Luffy out for not being an emperor and he still thinks he can kill him after the blud used 3 named attacks in his peak form
Zoro vs Lucci :
Lucci who thought he can kill Luffy changed his priorities just from nameless clash with Zoro ,
Lucci's intention :
From Killing Luffy and his Nakama is goated => to Killing No.2 Zoro and His friends is just enough => to just stalling No.2 Zoro is good enough
something Luffy couldn't do
