Find out if it uses Breton technology. If so, it's the same as every other major manufacturer, including Cambria. Not sure why anyone cares if it's a family-owned company as it's just another corporate enterprise. Warranty is similar among all of them.

Many of these less-expensive quartz manufacturers such as Hanstone have had recent quality issues and our local fabricators prefer not to work with them. I am not familiar with Atlas, and would recommend researching the brand more. Consider asking where they import their quartz product from, as this pertains directly to the quality and longevity of the product. Hope this helps!

Fabricators can buy no-name engineered stone in bulk, save a ton of money, sell just under the big boys, and pocket the difference by building their own brand.

Quartz doesn't have a sealer. It's quartz particles in a polyester resin binder.

In short, brand DOES matter. I read up on the rationale for Breton technology when I was hunting my countertops down, but afraid I can't remember (since I no longer need to) -- but Google will be your friend... Somewhere on the Web there is also a list of all quartz manufacturers that utilize Breton technology. THIS is what matters. Beyond that, it's largely what they have in the pattern and color you want.

Thanks all.

I did a stain test using ketchup, curry powder, pencil, and pen. I left all four for 24 hours. The ketchup came out completely, but the other three leave discoloration after I tried cleaning with a wet paper towel. However, I don't know if this is expected to be the case for white quartz of any brand. What kind of cleaners would you recommend?

I have a sample of white Silestone on the way. I plan to run the same test and see what types of results I get.
