With only a few chapters,this Eggehead arc is already better than Wano in my opinion! I guess it depends on what you like most about One Piece: if someone prefers the "big battles" side,Wano will probably be better,but if someone prefers the mysteries and the plot in general,arcs like Egghead or Zou are better than Wano,and this is my case. And so far,Egghead is even better than Zou! And we also had a big battle,altough still uncompleted,between Blackbeard and Law.
