I'll go Fury just because he hasn't lost yet. Wilder has had 3 fights that he didn't win by KO and 2 were against Fury. Also, at the time of the first fight, I thought the draw was BS and wilder should have won, so fury is probably mobbed up with judges in his corner.
Though, I can't really take the second fight win away from him. He wrecked Wilder worse than wilder wrecked him in the first one. I liked how he got everyone to sing a song post fight too. He became my favorite boxer at that moment.
