In a sense, I would have to disagree.
In terms of practicality and usefulness, Jeet Kune Do (invented by Bruce Lee) would be the ‘best’ to practice. I say that because it is not a style in itself, but rather a philosophy that one follows to transcend style, to go beyond the use of artistic and fixed positions and movements, so as to find the truth of the matter. “Truth” being the simplest and quickest end to a fight with an opponent.
The best thing about JKD is that it takes what is useful from all current styles. You are not limited to practicing a certain way. As Bruce Lee said, “Have no way as way. Have no limitation as limitation.” One can study Kung Fu, Tae Kwon Do, Judo, or any other number of styles in order to take from it whatever works best in a given situation.
The most important thing, I find, is that JKD is a philosophy one can apply to all aspects of life. While most martial arts only teach you how to fight, JKD can teach you how to live.
Unfortunately, JKD schools are hard to come by, most of which exist on the west coast in the US. I know of one other school in New York City run by one of Bruce Lee’s first students, but other than that you would probably have a hard time finding a teacher.
Whatever you decide, however, I would recommend picking up the book “Tao of Jeet Kune Do”, a collection of notes and martial arts concepts written by Lee. That book served as the backbone of my life in eastern philosophy.
May the Force be with you on your path of the martial arts
