I think the Colombo's and the Gambino's have always been the most flashy. One's had three wars, the other had a street celebrity that nearly brought the entire thing down. The Lucchese's were show offs when Amuso and Casso held the reigns, but the new boss Steven Crea seems to be pretty low profile, he's certainly less violent than Amuso was.
Overall the Gambino's seem to be keeping quiet with Domenico Cefalu as boss. But the Colombo's can't go a year without a fresh indictment being handed down against them.
