This is my first ever dishwasher, so I can't really compare it to others.  I always though dishwashers did a so-so job, but so far this one is really great.  Everything comes out super clean.  I'm just unpacking things that were in storage for a few years, so it's nice to have the sanitize feature.  I wish the washing times weren't so long, but I'm sure there is a reason why they seem to go on forever.  We are on a well and I worry about using too much water, but supposedly these machines use less water than hand washing.
