I have a GE Spectra with the flat top surface and am quite happy with it. It cleans up easily (Cerama Brite helps for the burned on stuff and it acts like a wax to keep it looking shiny.) I probably shouldn't say this because you could be in trouble if the cooktop is still hot, but it's like having extra counter space when you're not using the stove. Extra counter space is always a good thing!
All that being said, we only have electric available at our new home here in SC, when we lived in NJ, I had natural gas and a good old flame and I miss that a lot. It took some time for me to get used to cooking with an electric stove. With a flame, when you turn it down, it turns down right away (like under a pot of
boiling water) but with electricity it just takes longer. Lots of boil overs until I got used to it!
That being said: If I have to have an electric stove, I'll definitely take the flat top kind.
