Definitely Sonny. Gotti was more like Joey Zasa in GF III: loved being a braggart and loved the media attention. Needless to say, being a media darling is the last thing a criminal should relish. Sonny hated the media (as evidenced at Connie's wedding reception when he busted the reporter's camera). In spite of his hot-headedness, he knew when to cool it and play by the rules. Gotti had no rules. He preached them, but he didn't practice them. Three very basic rules he broke: (1) he had an affair with another made man's wife; (2) he knocked off a boss without full consent of the commission; and (3) while he didn't deal drugs himself, he looked the other way while some of his buddies did. And although Sonny was interested in "that white powder," he was going to listen to his father regardless. Sonny was at least don-material; Gotti just happened to be in the right spot at the right time and bullied his way into the position with no respect whatsoever for others. Gotti was an LCN unto himself.
