I enjoyed reading this chart but I hope it doesn't reinforce the bias that some fans have that word complexity is the only way to tell if a rapper is good or not. There are several ways to judge the strength and weaknesses of a rapper. Complexity is one of them, flow is another. Story telling ability is also another very strong in indicator. The best rappers are able to bring a mix while some are just so strong in one area that they explode no matter if they are really weak in other areas.
