In the 70s and 80s the bonannos were hit with alot of indictments and the Brasco Fiasco which led to them losing power among the comission, plus they lost Joey Bo which led to the internal wars they had, so yeah the lukes had more power in that era, but before that i have no doubt Joe Bo's family was stronger, he took over the Maranzano Family and planted his flag in canada and had the biggest dope pipeline. More money and influense i believe the bonannos were probably more powerful than the Anastasia family before Carlo Gambino took over.
