perhaps, but without a doubt Gotti is #1. That loud, obnoxious, attention-whore did more to harm LCN nationwide than all the rats combined. Even after valachi flipped things were still doable. Look at the 70's... it was like the wild west all over the country (i.e. Vegas, NY, Chicago, everywhere) Once he killed castellano and started that teflon bullshit, the FBI had enough.

But yeah, casso is a total scumbag. One thing I do respect about gotti is the fact he took his sentence like a man and never tried to cop-out like casso. Do the crime, do the time.
