It's really scary when We are +1100 Chapters & you have a Clear Idea on how Powerful are Supernova, Yonko Commanders, Warlords, CP-0, Admirals, Fleet Admiral, Pirate King, Yonko, Gorosei, Logia Users, Mythical Zoan Users, CoC Users, Nika, Seraphim, Giants, Samurai, Lunarians, Scientists ... etc you name it, it's there in those Chapters,
But "Greatest Swordsman" still reserved (Not even a Single Basic Haki Feat, even Joy Boy already showed his Haoshoku Haki & Imu flexed his Transformation & Executed Saturn), and soon you will witness Holy Knights & Loki & other Giants & everything Elbaph or Mary Geoise has to Offer, while Mihawk still waiting for Zoro & People crying as always
Oda already revealed Strongest Two by bringing them to East Blue,
Followed by First Paradise Island, showing Luffy vs Zoro where They asked: "I wonder which one is Strongest? Martial Arts or Swordsmanship?"
You should abandon the idea of ever seeing someone more Powerful than Mihawk or Dragon,
The only Debate that should exist is between these Two, the Rest are already Settled,
No Attack coming out of any Sword or Weapon can Top what Mihawk can Unleash,
No Attack coming out of any Body can Top what Dragon can Unleash,
