The Marcello, Trafficante, Zerilli, the KC fam, Rockford, Milwaukee, LA etc. operated independently to an extent BUT were mainly represented by other larger families on the commission. For example Trafficante worked with both the Midwest fams and the east coast fams. Same thing goes for Zerilli and some of the LA bosses. So its quite hard to say on who was more powerful, meaning between Marcello and Trafficante, since there were more powerful guys above them.

As for the question "who you wanna be"....I would like to be the guy who previously buried both Marcello and Trafficante in my backyard and planted cactuses on their graves, and later placed a pistol on your forehead for asking that type of question lol (just kidding )
