Colored Pencil debate (with myself)

I'm continuing my study of Prismacolor versus Polychromos colored pencils.  I purchased three red polychromos pencils so that I could do a good comparison between the blending of them against the prismacolor.

One of these was colored with Prismacolored pencils (the bottom one); the other with Polychromos.  A few differences:

• You might be able to see (in the terrible picture) that the prismacolor leaves a waxy finish. That isn't present with the polychromos - you're able to add more color layers with the polychromos.
• The prismacolored pencils are softer, and may be better for larger areas.  The polychromos are harder, and might be better for more detailed images.
• The prismacolored pencils, when you add too much color, shed onto the paper around the image. This I Really Don't Like.
• The polychromos don't break like the prismacolored pencils do. I can sharpen them to a better point, and they hold the point.  Also, there is less breakage inside the wood of the pencil - that drives me crazy with the prismacolored pencils, and results in wasted pencils.  

I'm still not sure what I'm going to do, but at this point I'm thinking I could use the difference kinds of pencils for different projects.  Also, the shedding of color outside the image and the breakage are really turning my heart away from Prismacolor.
