Steve Seagall is so arrogant (I remember when he was on some talk show, he rolled his eyes about Van Damme) that even in his prime, VD might have beat him.
Now, there was an early martial arts film with Jackie Chan as a side kick. Was he a serious fighter at one time? I know he does more action comedy now with his own stunts, but was he a serious fighter earlier in his career?
There's nobody that comes close to Bruce Lee. Even 7th Degree Dan Kung-Fu masters will say that Bruce Lee was an extraordinary technician.
What was his variant of Kung Fu called? The way of the vibrating palm or fist or something like that?
Segal is the real deal. Despite his lousy attitude, he is still respected for being the first white man to open a dojo in Japan. And considering this was an Aikido dojo, long considered to be too Japanese for gaijin to understand properly let alone master, that's huge. Still, his ego is enormous, and he represents the worst in how a martial artist should behave.
Van Damme had done competition in Shotokan and kickboxing, I believe, so he does have some fighting cred. I always liked him better as a star.
As for Bruce Lee, the style of kungfu he trained in was Wing Chun. He then expanded on the philosophy taught in his style to create Jeet Kune Do, which is not a martial art but rather a system. "The Way of the Intercepting Fist" is a way of thinking that breaks practitioners out of the rigid constraints of their styles, to do what works best.
In a fight between JCVD and Segal, my money would, sadly, be on Segal. His is the more street-practical style. Van Damme's Shotokan/Northern Kung Fu/TKD amalgam looks great on film, but it's not at all practical.
TKD is not even a real martial art anymore. Any style that punishes for hitting too hard and encourages you to drop your hands in a fight is just dancing.
