certain forms of kung fu are better than others.....a Kajukenbo master could get with a MMA fighter because Kajukenbo is several different martial arts rolled into one....there's Karate, Kenpo, Judo, Jujistu, & Chinese Boxing....so one could have a nice stand up game and still be able to take someone to the floor with jujistu and have a good ground game with the judo....
but everything all depends on the fighters tho.....some people are just natural fighters and others aren't
