Quartzite is great. Not to be confused with quartz, which is a manufactured material. Quartzite is natural stone, like granite. And you can get a quartzite that's white with gray veins, like marble, only it has a look all its own. Gorgeous, to me. I don't like the look of most granite countertops.
And just a personal opinion here, do not get dominantly brown granite counters. I mean, brown. Not a good look for a kitchen or anywhere.
I'd advise against marble. Yes, it looks beautiful . . . in the beginning . . . but it's no fun to take care of, and unless it's triple or quadrupled sealed, it's going to need a heckuva lot of taking care of.
