For me the best is Traditional Karate. In this name are few styles or how some people say's schools ( a way how someone teaches karate.) The main and the most know styles/school are : Shotokan, Goju-ryu, Shito-ryu alsow Fodokan(Prof. Jorga's school of Shotokan, how he said "Fodokan is elite of Shotokan"). For me the most important is if the style teaches us todome waza( the way how to destroy all offensive power of our enemy ). Then this is not a sport but a true martial art.
