I'm not sure that the European comics do more money than the manga, Europe has eternal classics with many years but things like One Piece or Kimetsu sold a lot. Speaking only from the point of view of money, but I suppose it would be a thread for long debate since I think that Japan has done more manga than comics that Europe has done but most of the manga are irrelevant and sell bad but still with little sum. to the industry, it could be an interesting thread to see what the industry generates, among its greatest exponents and all comic/manga industries.
