For the price of the toilet, I don't know, I was expecting something more.  We have a Toto in our current house and it has great attention to little details that I loved.  This one was kinda, "meh". I like having a dual flush option, which this doesn't have, but it is also only 1.28 GPF.  This went in our master bathroom and since we haven't moved in yet, I can't comment on whether it stays cleaner than the other two toilets we got (Jacuzzi) with the special glazing.  I definitely like the higher seat. BTW, it was packed incredibly well.  Bravo Toto!
