Any MMA fighter could take either of them. Im a HUGE Bruce Lee fan but if he entered the ring with any MMA fighter he would find himself on the ground punded into a bleeding pile of pulp.

But between Chuck and Bruce i think Bruce would SMOKE Chuck. Bruce devoted his entire life studying and redesigning the art. Chuck was just a martial artits. Bruce wa s a God.

I forgot to add. Bruce Lee was so fast Chuck wouldn't be able to block any of his hits. It would be over fast. Bruce was so fast they asked him to slow down in some of his movies because the camera couldn't film him.
