Looking to hear about durability and maintenance with the integral sink on HiMac (or Corian) counters.

I've searched here and not seen much. I understand early sinks from 10-15 years ago had some cleaning issues over time. Could folks with newer versions share their experiences? How to these compare to a light colored enameled cast iron or Silgranite - maintenance wise?

Thanks much!

(PS I have a Silgranite, so I already know they are great...)
