Rusty Rastelli was still able to whack family dissidents from prison and maintain power until his death.
I can't even argue with you on Joseph Bonanno, damn why couldn't he just roll with Carlo Gambino and Tommy Lucchese?
As for Sonny Black, the Bonannos didn't have their first rat until the early 2000s, over 2 decades after his murder. No way could he have seen that coming. I don't see any intelligence in the route he took, but still admire him for his principles.
As far as accomplishments, there really wasn't any in the grander scheme of things.
