Both Paul Rubens and Mungyo 72 color set costs around the same. Paul Rubens are way softer and easy to blend, better for layering than Mungyo which are not too creamy, can crumble when layering and blending, and some colours are reportedly bland. But at the same time Mungyo happen to be less sticky and oily and some beginners prefer them as they can't handle the softness of Paul Rubens.
