Product review (5 stars): After a lot of looking, the very best.
I can't say enough good things about this cook top - which replaced a once-top-of-the-line unit that was 17 years old.

The best things:  1) the right rear burner is intended mainly for simmering stuff.  On its lowest setting it will keep a pot of water (or whatever) at about 120 degrees - like, forever.  But it also gets hot enough to get oil to 350 degrees after about 6 minutes. 2) The center burner which has a double range. On high it can bring a pan to 520 degrees in under five minutes.  On low it can sustain water at a temperature of about 150 degree.

These two genuine simmer burners let me keep soups warm for hours or heat chocolate chips without a double boiler.

The thrid really great thing is that the cast iron grids are hinged and very easy to get out of the way for cleaning around the burners.. Also the grids are wel- and evenly spaced.  This makes the top look less artistic than some of its competitors BUT it means that there are no gaps on the edge of which some pots could easily tilt.
