I love Jackie, dude just oozes charisma, but Bruce wins on that no one can really match up with him in skill and technique, hell in physical strength and speed. There's a reason Bruce Lee rules the martial arts field and that is he was the pinnacle, Jackie is more of a superstar.
Jet Li I wouldn't put there with either Jackie or Bruce, he's awesome but not quite there yet.
well bruce lee may have been the best fighter, but I enjoy martial arts movies for the technical showmanship (emphasis on showmanship). Films where the choreography and acrobatics of fights are as important as the fighters themselves. I think Jackie Chan is a better choreographer than Bruce Lee that's why I rate him higher, not because he's a better fighter irl, that's irrelevant to me.
Also, perhaps more importantly, Jackie Chan and Jet Li had the help of people like Lau Kar-leung, Sammo Hung and Yuen Woo-ping for some of their best work like OUATIC and Drunken Master II. So it's not really the fighters themselves that make 'em for me, but more so the people behind their successes.
I would also put Donnie Yen up there with Jet Li and Jackie Chan now, he came into his own with the Ip Man movies but he was in OUATIC2 and Iron Monkey before that, so he deserves to be up there.
This sorta stuff impresses me more than anything in Enter the Dragon
