There's little doubt that the two biggest New York families, the Genoveses and Gambinos, were bigger and stronger than the Outfit. But to say that the smaller New York families were always bigger and stronger than the Outfit is highly questionable. It think the Outfit from the 1950s to 1980s was comparable to the Bonanno, Lucchese and Colombo families in numbers, and I'd even say that they were relatively stronger, considering that the Outfit controlled an entire city and much of the Western United States.
