Yeah . . . I think you could make the case that Natsu wins (via eating Ace), but the way they did this verdict makes it clear they did very little research into One Piece. Enel could maintain logia intangibility while F_CKING ASLEEP. Natsu would NEVER be able to hurt him through the means shown in the video.
I can only imagine they'll say "But that's Enel. Not Ace". I don't really follow One Piece series, so I don't know if Ace has done the same. But it seems, unless Ace already showed that he could maintain logia intangibility while sleeping, they won't include that. Well, even if there's an analysis error in that episode, this isn't the first time they do this.
Ace has been hit before so he's not as good at intangibility as Enel.
That said this was never a fair fight. Almost everything Ace has ever done in combat revolves around his fire powers. He's never used any Haki, except once as a kid, and his physical showings are almost non-existent. Sabo would have been a way better pick from One Piece.
