Lol, the Author expliclty hyped It as superior.
Kaido and Luffy didn't even reach Onigashima's highest floor.
Obv, since It proves you wrong.
Now making a better thing than Imu Is not relevant lol.
You are saying Harald in weaker than 1026 Luffy. Harald was conflicted, so you are saying Xebec failed to defate a conflicted 1026 Luffy as if It was a better take than Xebec himself being at 1026's Luffy level

.
1026 Is a strong fighter.
I am point out the absurdity of putting him near or even above someone stronger than prime WB.
