Technically a grand master is the best in the world in that particualr art. You can have lots of masters but only ever one grand master. It is kind of like the pope. You can only have one and you only attain that title after the previous one dies. There is often a hell of a lot of infighting over who rises to the title. It is not unusual for the art to split into two seperate arts so both contenders can be grand master. I hope that answers your question.
