I really love the range.  The two round burners give you amazing heat control and are very even heating. 

The two skillet burners are not very even, they heat in strips.  It works great for boiling water or soups, but I don't love using them for frying or browning.  The oven is very consistent and works great.  I would recommend the 800 because you will have 2 large round burners and 4 small burners.  Plus, you have autochef.
