According to Gemini:
One Piece, with its vast cast and complex lore, is bound to spark some disagreements among fans. Here are some contenders for the "most dumb" discussions:
Sanji vs. Zoro: This is a classic and seemingly never-ending debate. Both Zoro and Sanji are incredibly strong Straw Hats, and fans endlessly compare their strength, fighting styles, and overall value to the crew.
Power Levels: Assigning specific power levels to characters is a tricky business in One Piece, where strategy, matchups, and plot often influence outcomes. Debates about exact power levels can get nitpicky and repetitive.
Worthless Crew Members: Disagreements about the usefulness of certain crew members can get heated. Some fans might downplay the importance of Nami's navigation skills or Usopp's ingenuity.
