Well ...everyone is gonna have something different to say, and I do think that their are many styles that work well but most of them concentrate on one thing..for example judo is primarily used for ground combat etc....I am a big fan for Muay Thai as being one of the best not only martial arts but sports out there...It consists of using your Hands, Feet, Elbows, Knees, Clinch Work, Counters, etc....even taking your opperent to the ground is used.....you have to consider the over all not just what seems to work well.
