This is our first experience with composite granite, all other kitchens have always had a stainless steel sink.  We just installed a new kitchen in a condo and had limited space for a sink.  So far (after a week) we really love this!  The depth is great.  The single deep bowl is much more convenient than a double bowl sink.  The shallower compartment on the right with the stainless steel drainer basket is so versatile and often eliminates the need for a dish draining rack when washing up only a few items.  The basket is also useful for food preparation.  The biscotti color also complements our new quartz countertops.  Since the sink is so new, we cannot comment on either the longevity of the composite granite vs. stainless or on whether it will stain/discolor but will be happy to update later on :-)
