I like the look of both granite and cultured marble with a 'granite' look. The marble has the one piece with the sink included. The granite would have a separate porcelin sink. What is the better way to go?

This is all about cost and what YOU like really!

In my opinion, they both are good choices. I've installed both kinds (quite a few, actually) and have never noted any issues in particular.

I hope that helps somehow... ;)
