Having lived with my cooktop now for a month,  I have adjusted to the differences between my old and the new.  It does a pretty good job, and I like it. One criticism are the grates, which are a straight line. Having the burners defined as in the older model, makes it easier to know you pan is centered.  I am sure I will adjust, but that's my critique. The straight lines do look very cool and it's a beautiful appliance.
