Aside from the Genovese and Gambino families which I know is often the automatic default answer for a question of this nature. Which one particular Mafia "Family" (or families) do members of this forum feel were the most successful in terms of profitability, tenure, and had the least amount of problems such as in-fighting, wars, or arrests and imprisonment throughout their history?

Have at it guys. I'm genuinely curious as to how others perceive this.
