I have to agree with special kid Timmy to an extent. No art is better than another as such, just some arts are designed to fight. Boxing is the sport version of fist fighting, something that has been around since goodness knows when. It has been found to work and to hurt and so on. The fact is, some arts are meant for fighting and are superior to others for fighting. Bas Rutten trained in TKD, but he switched to MT when he saw a MT'er completely leather one of the people in his class. He learn JJ because he had no ground game. Honestly, Ninjutsu people often say 'Ninjutsu isn't designed for a ring thats why it isn't used in one, we don't need to proove ourself etc. etc.' well the fact is Until a ninjutsu person steps into a ring toe to toe with an MMA'er or similar we will never know how the systems compare.
