I fee Pea was by far the better ring general and had a more fluid offense. They are certainly close in skill level but I feel Whitaker had more tools at his disposal.
Floyd with the more sound guard and has better balance. A better straight/cross too, but that's all I'd give him. Whitaker as the better general, better jabber, better off the backfoot, better head & upperbody movement, better on the inside, probably better punch placement (mostly to the body - he was superb at that), and better with feints (particularly at not falling for them). I'd also give him the edge as a combination puncher and would say that he was clearly just flat out better at integrating his offense with his defense. So yeah, Pea.
Bit like picking a favourite son for me. You want it to be your younger son but you know the oldest is academically superb,if a bit less fun.
Floyd definitely knows how to win and is a better fighter than Whitaker. Whitaker has a better resume though. Whitaker with better pure skills. Floyd better balance/right hand/IQ/Adaptability. Whitaker better jab/left cross/left hand/Fighting on the back foot
Not falling for feints is the trademark of a great fighter. Both Whitaker and Chavez both amaze most not when they move in reaction to a punch, but when they stand perfectly still as one falls just short of hitting their mark. It's especially impressive on the inside, their peripheral vision must have been something else.
