Roberto Duran was a master of the feint. Bernard Hopkins was excellent at feinting, even to a point when he got old and feinted too much instead of throwing. Roy Jones and Erik Morales were effective feinters. Sam Langford and Charley Burley were known for being very good at feinting their opponents and using them to great advantage.
The best feinter is the one that uses feinting to land the most advantageous punches. The ones that cause knockouts.
My two picks would be Moore, and perhaps Fitzimmons. If we allow that a feint isn't always a punch, it can be a faked step or movement. Moore, after he had his gall-bladder was removed, used to feint openings in his defence exposing his (perfectly painless) scar tissue with a view to countering the punch the opponent didn't yet know he was going to throw.
It's on his stomach. Check out photographs of Moore late on. The famous Durrelle photograph with the towel over his head is a good one, you can see the scar tissue beautifully. Moore nearly died post operation, he was really unwell, and the rumour went around that he was troubled by body shots (knowing Moore he had something to do with these rumours) - the idea was, expose the body, induce the lead, have the counter prepared.
Duran is a great example, constantly hyper-active with his left, annoying his opponent, and oh B-Hop, can feint in ebery way, subtle feints with body movements to perfection. I think Jersey Joe was very good also
I'm not doubting the ability of the aforementioned and their ability to feint. I just wonder how often a fighter starts to throw a punch, changes mind and throws a different punch, and has us thinking it was a great feint when it was really just a change of mind. I've been drinking again. Forgive me.
Jersey Joe Walcott with his triple jab, jab to the head...feint to the body......come back with a jab to the head. against joe louis.
Not the best feinter, but Howard Davis, Jr. was noted for striking at the head while looking at the body. Tunney was very much impressed with Corbett's feinting when they sparred. Early in their first fight, Pastor reported that he could feint Louis into knots. Fitz was known for getting out of jams with his ability to feign distress convincingly, suckering opponents into leaving themselves wide open for an opportunistic counter attack. Carl Williams followed Mike Weaver to the ropes after landing an apparently stunning blow. But during Carl's subsequent flurry, we see Hercules positioning his left, not against his head in peek-a-boo fashion as he did after getting floored by Dokes, but cocked at his waist, ready to be uncorked for beating Carl's right to the punch.
Roberto Duran, by far the greatest master of the feint that I've ever seen, and there have been many other greats to consider after him. The fight against Palomino was the greatest example of the feint. He was masterful against Palomino. He seemed to intimidate Carlos with feints.
