Bought a Kenmore induction cooktop back in July. Previous to this, it was an electric. I have some experience on gas in a house I rent a few years back.
I love induction. I can boil soup in less than a minute. Temperature control is amazing, and the response time is immediate. I can be boiling water on high, then I turn the burner down to low, and the water instantly stops boiling.
The Kenmore only has about 20 settings (.5 increments) but I find that's more than enough. On the very lowest setting I can temper chocolate.
I think, if I had the money, I'd get a really nice gas stove... but induction seems to be almost as good at the fraction of the price.
