Sounds like someone is interested in validating his own style.
Why else would one come to a Japanese Arts forum, and bring up
a Thai style? MTisGreat, are you looking to try to convert people,
or just argue with them?
I'm way late but have to throw my 2 cents in. It's less a function of the styles involved but how they are trained. Any style trained in a functional and realistic manor will have an advantage over someone training in an unrealistic way.
Every once in a while someone comes up with like question this. It always reminds me of when I was a kid and someone would say "Superman can beat up Batman"
I mean Yeh it is kinda of silly but one must remember that that was the basic premise of the UFC when it first began. So I guess alot of people really never gave up comics.
Now this was told to me by a guy who trained in Thailand. He was at one stage the Muay Thai champ of New Zealand. His name is Terry Hill, if you check his background, he is all that and a bit more.
First he told me the stories of the great Kung Fu masters that went to Thailand and got their asses handed to them by the Muay Thai guys.
Then he told me of the great Karate masters thet went to Thailand and got their asses handed to them by the Muay Thai guys.
Then he told me of great Judo players that went to Thailand and handed a bunch of Muay Thai guys their asses.
Now you have to remember that all these fights were fought under Muay Thai rules. These Judo guys are the reason that ground fighting is not allowed in competition these days.
Q: You want to know who would win?
A: The side that changes the rules to suit themselves.
If you mean without rules, then it would depend entirely on the practitioner.
