Between Corian® and granite, which material is more suited for the kitchen countertop?

Marble and granite kitchen countertops are subjected to an anti-stain treatment to protect them against the penetration of liquids. Kneading on a marble or granite surface is not hygienic because the natural micro-cracks in these surfaces can hold bacteria and microbes that may contaminate food. Corian®, on the other hand, is non-porous and thus unsuitable to the proliferation of bacteria. What is more it is not stained by common substances found in the kitchen. Additionally, it is certified as a material suitable for direct contact with food products.
