If function is your primary concern, then the only material to choose is the one professional kitchens use: stainless steel. It won't be as good looking depending on your tastes, but it will beat most stones on other properties
What is the cost though? Is rust a concern? And of course, looks are a concern, but I imagine quartz is relatively cheap because many, many people can afford it.
It's not very expensive, though I can't give you a price since I live in a rental apartment. As for rust: not a concern with stainless steel, our kitchen is almost 20 years old and the steel countertop and sink still look immaculate. A bit of steel wool or polishing paste are enough to make it look like new. If it wasn't for the look I bet most kitchens would come with stainless steel countertops
