I do not have personal experience but I can provide information regarding sandstone countertops.

Sandstone countertops can be durable and resistant to scratches, but they are not scratch-proof. The hardness of sandstone can vary widely, depending on factors such as the amount of quartz present in the stone. Generally, softer sandstone is more prone to scratches and damage from acidic substances. To keep your sandstone countertop in good condition, it is recommended to avoid dragging heavy or sharp objects across it and using cutting boards when preparing food. Regular cleaning and sealing can also help to protect the surface from scratches and stains.
