In terms of big bangers, I always put emphasis on the two-handed bombers. Guys like Hearns, Trinidad, Frazier, Foster, ect get brought up a lot in these discussions, and rightly so because they sent a lot of guys to the hospital, but they were known primarily for one power hand (or in some cases, one power punch). Tommy's piston right and Foster's cannonball left hook were two of the deadliest punches in boxing history, but Tommy didn't really knock a whole lot of people out (if any) with his left hand, nor Foster with his right.

Guys like Jackson, Tyson, Bazooka Gomez, ect could put a guy out with either hand and seemingly with any punch from any angle.
