In my opinion the Gallo's crew is hard to beat, when you take into account what they did, tried to do and then how successful some of the members became later after the crew disbanded it's hard to beat. Three future bosses and plenty of real gangsters and killers among the others. Thoughts on other crews?

Joe Gallo – murdered in 1972 by Colombo gunmen
Albert "Kid Blast" Gallo Still around with Genovese
Larry Gallo – died of cancer in 1968
Frank "Punchy" Illiano Recently died after being transferred to Genovese family in 1975
Bobby Boriello - transferred to Gambino family in 1972
Nicholas Bianco – transferred to Patriarca family and became boss I believe
Vic Amuso – transferred to Lucchese family and became boss
Joseph "Joe Pesh" Luparelli
Joe Gioelli
Carmine "the Snake" Persico – became long time boss of Colombo family boss, died in 2019
Michael Rizzitello - transferred to Los Angeles Crime Family
