I dont think its good to compare both of them as both have different styles of fighiting so according to me both are good in their own field
Indian as well all others country people they like most Jacky Chan. preferably both of them are legend.
i like Jackie Chan for Comedy n action but my favorite martial art hero is Jet Lee for the action films.
Some people ought to keep in mind that the question here isn't who would win in a fight, it's who you like better. It's an interesting divide because Li, having dozens of medal from various competitions, has a really authentic form and has hard hitting combos. Jackie Chan, though, is a performer. This isn't to say that he's any less authentic though some people take that to be the case, and he's probably more athletic because of it. He has more "showy" moves, which make for a more fun viewing experience if you're not a hardcore martial arts aficionado. I like Donnie Yen.
These are two legends. But I like Jacky because he is so funny like me. And don't like Jet lee because he is like my PAPA (no funny games boy~_~).
