Who's the hardest hitting heavyweight of all time?

Why do people bring up Wilder when against the 3 best fighters he faced (Fury, Ortiz, and Stiverne) he is 4-2-1 (3 KO's)? I think there are plenty of fighters who would have his KO record given his competition and when he leveled up, he stopped getting KO's. There are plenty of bigger punchers than Wilder who knocked out world class competition and not a bunch of stiffs.

It's like people who hold Mayweather's undefeated record in high regard when there are plenty of fighters who would have the same record given his level of competition. Like if Mayweather had faced the same level of competition as Oscar De La Hoya, he would have multiple losses on his record.
