Quartz is easier to keep clean and you don’t have to worry about sealant. Granite has little tiny micropores that can get stained a bit easier than quartz and granite does break a little easier than quartz. However, granite can withstand any kind of heat, while quartz can only withstand about up to 425 degrees before you run the risk of it becoming scorched. Light scorch marks on quartz can be smoothed out, but heavy scorch marks on quartz will not be able to be removed.
