So exactly what is it you are looking for? You say Lewis doesn't have personality but If it's personality you want then Joe Louis certainly doesn't belong there.
Last time I checked Fury toyed with Wlad and became depressed because Wlad put up such a poor fight He is infinitely better in almost every department & doesn't get chinned by guys like Sanders. Fury is the first of his kind and he is even a step size bigger than the standard for "modern superheavy" so him having the stamina and movement for his size is literally an evolutionary leap ahead. He didn't just set a new meta he jumped an evolutionary wall. We will go back to big dossers like AJ & Wilder when Fury has gone. Hell we even have a skilled little man in Usyk coming up to exploit the flaws of modern heavies like AJ. Who cares about Wlad he just maintained the standard that Vitali & Lennox created by clinching midgets to death
Louis was loved by white America because he was so humble, his fame was huge specifically after beating Schmeling at the time of the tension between the US and Germany during the WW2 conflict, Louis endeared himself to the US public by joining the army during the 40`s. Frank Bruno was loved in the same way by the British public and he was more popular than Lewis, he was warm and funny while Lewis was a loof and wooden.
Fury is better than Wlad was in every way except in terms of stopping fighters, Wlad`s body mechanics were better so he punched more cleanly.
Marciano was white but that wan't his main attribute or claim. He was the only HW ever to retire and remain retired undefeated.
