"Is quartz (engineered stone) stronger?"
It depends upon how you define "stronger". Corian and other solid surfaces are much more chip resistant than estone or natural stone. Estone can be cantilevered further than natural stone, but since edges on Corian are usually built down, that would easily cover steel tube underlayment, practically making it "stronger" then either of the alternatives.
As the guy who gets the calls to fix the chips, I can say that yes, there are people that bash pots and pans against their countertops daily, especially at dishwashers. That's why you specify a slight positive reveal at undermount sinks beause the sink now protects the bottom of the sink cutout edge from chipping. Designers love the pencil edge, but you're not calling her when you've got chips to fix are you?
