This is all cool and all, but goes to show how deep fan cannon goes. I literally just rewatched the buu saga, in detail, particularly the part with kid buu, and kid buu is indeed more powerful and stronger than buuhan. This is confirmed by Goku who says he's at least twice as strong as his previous versions, as well as Vegeta and the others, I know logically it shouldn't be this way, but statements in battle hold higher ground than assumptions and things said outside the show and manga.
