this is a hard one, its like comparing pacquiao and floyds speed, both are fast but have different type of speed.
exactly Ali had quicker feet no question hand speed you could argue either one but i tend to think Tyson was slightly quicker
I think the fact that Tyson's hand speed was comparable to Ali's in spite of the fact that he threw every punch to knock his opponent out is proof that he had the greater hand speed. When you take power off your punches, you throw faster.
ali in hands and footspeed, but tyson got a very fast upperbody movement and his hands are quite fast too. overall i have to give it to ali even though tyson got ali's upperbody movement beat by a mile.
