I think the real difference is most use gimmicks WWE style to try get publicity where somebody like Mayorga or a Tyson Fury are genuinely a bit warped.
Broners persona just gets on my nerves, I can't stand the sound of his whiny voice and its the same thing recycled over & over ''Y, know! A.B - about billions! Floyds my big bro, y'know! Anyone can get it! I'm a can-man, y'know!'' Its to the point I have to just mute him.
Tyson Fury is such a goof he really is and I can't help but find him hilarious. I think hes a brilliant sh1t talker and feel a lot of its unintentional.
