With the introduction of the new Derwent 150 set of Chromaflow, there has been a lot of talk about the Chromaflow and comparing them to other popular pencils. Only a few days ago I created a post comparing the Derwent Chromaflow with the Derwent ColourSoft, which was a popular comparison, however; I think it is safe to assume that the most sought after comparison is that of the Prismacolor.
