Both quartz and granite countertops are highly resistant to heat and scratches, but there are some differences to consider. Quartz countertops can withstand high temperatures without getting damaged, making them ideal for avid cooks. However, they are not entirely scratch-proof and can be damaged by excessive force or sharp objects. Granite countertops are also heat-resistant but can be more prone to scratches. While granite is generally durable, it is recommended to use cutting boards and trivets to protect the surface from potential damage.
