I ll go with Shawn
I don't care if he reformed later.
Hbk in mid 90's is the biggest as***** in business perhaps
He held WWE and Vince to almost ransom when WWE was at it's most vulnerable period.
He didn't want to lose to Austin
He wanted to bury Rock
He screwed Bret
HHH is better than Shawn according to me.Atleast he puts over talent(Batista,Orton,Cena,Sheamus,Jeff Hardy,gave relevance to Flair to the modern fans).He has had his share of burials too but Shawn is a bigger dik than him
