Colored pencils decluttering - Brutfuner, Prismacolor, Markart...Which ones would you keep?

I tried couple of different colored pencils on Strathmore toned tan paper because I want to sell some of them. Some pencils worked better, some worse but remember that this was only the test on this paper because I want to use them on this paper, it does not have to mean that these pencils will not be better on other papers.
