Conteh. Much harder to counter. Ike's jab was stiffer but lots of right hands came over the top of it.
Agreed with Zadfrak. Ike's jab is extremely overrated. Some people honestly argue he had one of the best jabs in history... I'd say absolutely not. Ike's jab was robotic and predictable. A very hard jab obviously, but it did indeed get countered a lot.
