Let’s see I have taken one day of judo during summer sports camp, maybe a week of wrestling in Junior High and three months of Kenpo Karate. Now that the Karate Kid has been taught real Kung Fu the question becomes who's kung Fu is greater?
If I am following the UFC history correctly most tournament Karate fighters, even those who talked about their street fighting applications did not fight, it was like amateur boxing where a weak hit scored the same as a strong punch. Then a bunch of Brazilian guys came along with a challenge. The various karate types did their sparing routines and with their tournament scoring but don’t really hurt punches and kicks and the Brazilian guys ran right through the scoring hit grabbed the guy took him to the ground and made him submit through a pain submission hold. Meanwhile the Muy Thai kickboxers and boxers who did try to hurt with their strikes came up in a sport where the rules protected them from being taken down. So if the Brazilian got by their strikes they were also toast.
So the Brazilian Ju-jitsu guys dominated the sport and proclaimed their Kung Fu was the greatest. While this is going on a bunch of wrestlers, with no Temples or mystic energies in their history who had graduated and were left with WWE sports entertainment or nothing were sneering think no way Brazilian dude gets me on the ground as that was what wrestling was about, controlling who went to the ground. With a chip on their shoulders like the Brazilians had the wrestlers were able to control when the fight went to the ground and by now nobody was pulling punches or fighting amateur boxing rules where any strike scores no matter how hard scored the same.
So now we know any sport is constrained by its rules.
In the real world who fights one on one in the first place? Someone starting a fight is bound to have buddies around and if you take a guy to the ground. Well then you don’t need Tae Kwan Do to reach the head to deliver a fatal kick

So who's Kung Fu is the greatest?
