Wow. Sad. Jackie Chan's style is extremely different than that of Bruce Lee's. Chan's is more for entertainment and relies heavily upon improvisation and props. Lee's is more about brute force and speed. As is Jet Li's. Both Lee and Li studied wushu. Obviously Lee did much more martial arts and brought it all into Jeet Kun Do. You see, different styles.
Again, Li and Lee both use primarily wushu. . .
My personal opinion. I love them all. Li, Lee, Chan, Norris. All are very good at what they do.
