Planning to replace my countertops and can't decide which product to use. I love the look of a seamless sink. I have been pricing Corian & Granite and there doesn't seem to be much difference in price in my area. I heard some horror stories about granite...can stain, needs to be sealed. I'm torn. I don't want to put in granite just because it looks more expensive. I cook a great deal and spend much time in my kitchen. Would appreciate hearing your pros and cons. Should I consider quartz?
