Who left behind more as a: a) Heavyweight b) Athlete (Boxing & Kickboxing for Vitali and Boxing & Wrestling for Primo) c) Figure in popular culture/ in the eye of casual audience (books, media coverage etc.)
Carnera had a book and had 2 films made based on his story,he appeared in several films ,and was a hit as a wrestler.Vitali went into Ukrainian politics. It's Carnera by a clear margin. H2H Vitali beats him to a pulp ,but the quality of their resumes aren't far apart. The difference being nobody paid any of Vitali's opponents to lay down, as far as we know.
