It comes after Fury, the world heavyweight champion, recorded a dominant victory over Derek Chisora at Tottenham Hotspur Stadium.
Chisora's name has been added to a list of those defeated by Fury, including Deontay Wilder twice and Wladimir Klitschko, who saw his 11-year undefeated run ended by 'The Gypsy King' on the way to unified titles.
Joshua, meanwhile, has not been on the same trajectory as Fury having not returned to the ring after coming off back-to-back losses to Oleksandr Usyk.
But Hearn, Joshua's promoter, believes the Watford-born boxer boasts a more impressive track record of wins when looking back, which also includes Klitschko and the likes of Alexander Povetkin, Andy Ruiz Jr. and Joseph Parker.
"Tyson Fury calls everybody out and says everything, that's just not AJ's style," Hearn told Pro Boxing Fans.
"His (Joshua's) resume is in a different league to Tyson Fury. Tyson Fury has fought Wladimir Klitschko and Deontay Wilder, that's it in terms of elite heavyweights. I know Dillian Whyte was a good fight but I'm talking about the top, top guys consistently.
"He's always thrown in a couple of easy fights, whether it's Tom Schwarz, whether it's (Francesco) Pianeta, whether it's Sefer Seferi, Christian Hammer, all these guys. AJ, over the last whatever it is 10 fights, hasn't.
"Look, Tyson Fury is an outstanding fighter but Anthony Joshua is just not Tyson Fury. He's not going to go out and start slagging people off, getting in their face and calling them dossers and rabbits and gappy-teethed, it's just not his thing."
