Katakuri is alot more relatable and human than Doflamingo
I like DD a lot, but I actually think Oda botched his character the hardest among the major villains, his arc wasn't original, his actions weren't original, his fight was tremendeslly boring, outside of his past everything about him was generic
I don't think its over for both character tho, they will get more development in the future so we shall see, I really want Oda to do DD justice
also, the result of the poll is not surprising, but outside of this forum their popularity is about the same from what I saw
