For me it's CG. Like Big Tuna said, probably the single most interesting mafioso of all time. When I first started learning about LCN, the 5 families etc CG always stood out to me - I saw the documentary about him around 4 or 5 times probably (the one that's on YouTube).

I liked how in the documentary they said he never flashed his power, or wealth, but only on his car he had license plate that said CG1 which was apparently a "flex" in that time? Can someone confirm that? I mean I was born 20 years after he died and everyone and their mom right now seems to have customized license plates lol.

But yeah, Carlo Gambino gets my vote on this one.
