I purchased the LDTS5552D for the steam option and its high reviews.  I really like the ability to run a light load for only the top or only the bottom racks.  The heavy duty cycle was able to remove iced tea stains from a jar. I'm very impressed with the  cleaning ability of this dishwasher.  It also dries much better than any previous dishwasher I've owned.  Its quiet and efficient.  I set it usually on auto with steam and the dishes come out clean and dry.  The 3rd rack for silverware is a game changer!  Its easy to load and unload without bending over every time I want to put silverware in there.  Its not deep enough for a ladle, so I put those in the silverware container in the bottom rack.  Its very convenient to have both.  I'm very happy with this dishwasher
