I'll catch heat for this, but Accardo 1000%. If you'd ever met the man, you'd know. Granted I was a kid (about 13) when he passed away, but very classy and raised a great family. Castellano should be up there too. After all, he was always thought of as more of a business man. Maybe Frank Costello? The old school guys just seem to be on another level when it comes to class. They must've started putting something into the water nationwide after WW2 that turned guys into pitbulls.
