Depends what metric you are using, if it's by boxing ability then Tyson Fury, if it is by resume than probably Taylor and if by impact on the sport maybe Joshua.
Genuinely curious on the logic of Joshua being the greatest - does that mean you’d consider someone like Jake Paul who is having a huge impact on the sport to be one of the greats worldwide?
In terms of Impact on the sport, in the UK, Joshua has popularised the current boxing era. I do not consider Jake Paul a boxer, he is an influencer who does exhibitions on the side. He has helped to promote women's boxing however using his fame to give Serrano a bigger platform.
