Oh man, there's really no real form of karate. It's modified and used so effectively. You have Shotokan Karate and Kyoukoushin Karate. I see no superior form, but people say Kyoukoushin Karate will ALWAYS beat Shotokan Karate. Lyoto Machida, a great Brazilian/Japanese Karate fighter uses his father's modified version of Shotokan Karate aka. Machida Karate. It's just so unorthodox..the stances and use of effectiveness is more based on quality of technique than power. The base was originally formed by Lyoto Machida's father to use on men larger than him, and it's worked thus far.
