What's the best martial arts to master?

I wouldn't say there is a best out of the 3 you listed because most people do martial arts for different reasons, so one could be the best for you and not the best for someone else. For myself the best martial art is the one that is the most practical and applicable for actual combat. just look at the three, see what can be achieved in them, and chose the one that will guide you to what you want from martial arts.
