POSCA vs Crayola - Paint Pens do battle

Can one of the most well known "art & craft" brands, Crayola, take on the most popular paint pen brand, POSCA? The POSCA'S set me back about $3.30 per marker and the Crayola are not much less at $3 per marker. So, the quality should be similar right? I put both to the test on sketchbook paper, glass, metal, wood, ceramic and canvas. Some of the results might surprise you.
