Fury is funny, but it's also act, so you will get bored very fast, and Fury/Wilder pressconference was watched by 30 times less people than Khabib/Conor.
If we talk about quality of trashtalk Bisping was very good, Conor is more clown and showman, than trashtalker. Different type.
Plus lets not forget: Fury has one significant win in his career and it was decision vs out of prime 10 years older Klitschko...
Fury is preaching too much for my taste and Conor, Bisping, Chael are basicly not pretensious at all, so defy UFC most famous trashtalkers/showmans >>> Fury, with all respect for him.
Conor is also better seller, because he is talking like avarge bloke, when Fury likes to show he is intelligent guy, and it's unnecessary, but it's good to have pride youre smart guy.
Conor's trashtalk is more calculated it's not only about oponnent, but irish drunkards who will buy tickets and ppv, because they can relate to Conor.
So trashtalk can't be pretensious for me, and Fury sometimes is pretensious, if you know what I mean.
