I have had both Corian and Granite - the Corian for less than a year (moved) and the granite for about 5 years in our home up north. Have never resealed. Also have an undermount sink (stainless steel).

The Corian sink stained easily, and the countertop got scratched by and unnamed someone's keys (I think - best to move on).

Our granite is a dark sandy color (tannish), hard to see anything unless you get down to eyelevel. No chips/stains, love it.

In TV, we still have formica, won't replace until it shows wear/tear or is damaged. It's 5 years old as well. Once I do, will probably go with a granite even lighter than sand color, just for something different.

As for the sink, I might do the black/brown one (not sure of the material) as both ceramic and stainless also show stains/scratches. My sister and a friend have one, and it looks brand new after several years.
