Reviewed and compared several model dishwasher and choose this model because of cost and matching Profile series appliances. I had a Kitchenaid model that stop working. If I was to compared the Kitchenaid performance to my current GE one, I would say the dishes come out cleaner and the unit is very quite. 
I completed my own installation and it was not hard. I would recommend purchasing the GE accessories along with the washer (power cord and water line hook up) It will save you a lot of time during installation.
