Okay I'm going to be honest here, demon slayer has a good story, pretty good characters of u ask me and also good animation and One Piece has good story, amazing characters and the best manga I've ever read in my life, saying One piece is better than demon slayer or demon slayer is better than One Piece is just so unfair both are great animes and one of my favorites and neither of them deserve any hate the one piece manga is Amazing and the demon slayer animation is amazing, I'll always love both and never hate one of them!!

( Btw my favorite animes

1- One Piece

2- attack on Titan

3- demon slayer
