The most important criteria for me when selecting a toilet are, fit/finish, water height in bowl, noise and of course discharge.  This toilet checks every mark.  Fit and finish is outstanding.  This is a very quiet flusher.  I own other American Standard toilets, this is by far the quietest.  The water in the bowl is the correct height with plenty of real estate remaining above the water line.  Installation was easy as well however, the unit weighs around 90lbs, so plan accordingly.   Only criticism I have is the seat.  While its comfortable and fits the unit well, it is a bit chunky looking when compared to the nice modern look of of the toilet.
