|Bruce and Jackie in "Enter the dragon"|
|Jackie Chan,Rush Hour Movie|
I will answer in a very straightforward manner. Jackie was a better stuntman and comedian but Bruce was a true martial arts master. Lee used filmmaking to prove and to demonstrate his fighting theories while Jackie exaggerates often by adding wild stunts and a lot of wire work. If you watch Jackie fight, you will be entertained but when you watch Bruce, you might learn something. Jackie appeared in Bruce Lee's breakthrough classic Enter the Dragon, as one of the numerous people Bruce fights off. Although only on the screen briefly, Jackie's face can clearly be seen.
As Jackie said himself after his success, Bruce Lee could not be replaced.
