Can anyone share first hand experience of their TopZero sink? Have you experienced excessive scratching, do they drain well, do you have any regrets?

The few posts I've found are photos of retrofit TZ sinks (thank you Joseph C. for sharing your photos!). He seems impressed with their quality, but they appear to be 18 grade stainless instead of the much preferred 16 grade?

I found a few posts from homeowners who like their Create Good sink, especially the sleek drain design, but that's not an issue for me since I'm planning to install a batch disposal which eliminates the needs for a rubber flange in any sink.

Joseph C., have you installed any porcelain TZ sinks? In addition to TopZero stainless sinks in our kitchen, prep and coffee bar (3 stainless sinks total), we're considering two TopZero porcelain sinks for our primary bathroom.
