We love the flat top surface and we love the convection oven / air frying ability.  We had to turn the oven 35F up to compensate for cook temps.  Although the oven manual says you can put foil on the lower rack (catch drips from frozen pizza on rack above), it does hinder the pre-heat time since the heating element is built into the bottom of the unit.  If you take the foil out the oven heats much quicker.  On to the burners.  We love the power boil feature which rapidly heats water, soups, etc.  We love the warming element.  We are still fine tuning techniques for using the other elements as they are not as sensitive to knob changes as our old GE range was.  We did buy a griddle to straddle the 2 left elements for making pancakes, eggs, etc. and that works pretty well.  Overall, we like the new range, just have some differences to overcome after using the old range for 32 years!
