Having had both, I'd go for gas (that's going in my current kitchen as soon as I can afford it!). You have lots more control over changes to heat, and most new cooktops/ranges have the option of a super low simmer setting, which you can't find on electric.

I've also used induction (once) and was impressed by how quickly it heated things up and how the surface stayed cool (good if you have small kids). The downsides are that you might need to get all new cookware and there are limitations on the kind of cabinet it can be installed in (can't use drawers below as it throws the heat off to the bottom and it could be a fire risk).

Pros- the food taste so much better
control over changes to heat
Cons- more pieces to clean

Greater control is probably the biggest advantage. Electric ranges work in 2 modes, On and Off. When you set a burner to High it is just "on". When you set a burner to low, the electric alternates between on/ off to adjust the temperature... It heats up, when its hot, it turns off, it cools, then kicks it on again...etc... The oven will work in this same way.
With gas, this control is set by your flame and it never goes on and off and on again.
Gas will have a lot more parts so a feature to look for are how easy are they to clean.
You should also look at the amount of BTU the burners can put out as well as how LOW it can go too ( for the best simmering, you want low!)

Gas, you are in control, Electricity, you're just along for the ride. Seriously,
had electricity for years then remodeled and got gas. LOVE IT! You know exactly the heat you're getting as you can literally see it. When you turn it down, it's down, you turn it up , it's up. Electric - you have no clue what it's doing. You will not regret switching to Gas.

I agree with these guys. I grew up in a house with gas, but when we moved out to AZ most of the places had electric, after living in an apartment with an electric grill for a year, a gas-hook up was a HUGE plus in the house buying process!

I agree with the electricity to gas - way more efficient, stops and starts faster for instant heat. The only downfall of gas is the distance to your overhead hood fan and/or microwave. The space from the cooktop to the underside of your overhead fan increases to 30" (standard) with a gas range. If your cabinetry is too low, you'll have to bring that up to code too.

Glad to see this posting. Had just mentioned last weekend, after all of the Thanksgiving cooking/cleanup how I really would like to see what the cost would be to covert to gas. I thought I would love a smooth surface cooktop...I do NOT. I never had to scrub with a traditional coil electric and the two gas stoves I had years ago in different homes were no more difficult to clean. The glass top is a constant nightmare to scrub stuff off the top. If something spills or boils over, it cooks onto the surface immediately. As others mentioned, loved the turn it on and your cooking, turn it off and it stops, you get with the gas range.

Any estimates on conversion costs?

Just converted my glass top electric stove for natural gas. The gas company didn't charge for the gas line from the end of property to my house. But they did charge $500 to run the lines from the outside to the inside of the house ( had to go up through the attic and down the kitchen wall. Got several estimates from private contractors, and the least expensive was with my gas company. Installed a JennAir gas top with electric oven. LOVE IT.

Being a kitchen designer, I have had clients requesting both. One possibility is to have an 2 burner induction hob and a 2 burner gas hob. My clients who have magnetic induction are very happy. The venting is easier with electric as well.
I personally have converted to gas. My gas cook top is wonderful and I would replace the gas hob units I have for more modern "gas" equipment in the future.

janeilene...thanks for that info. I was "guesstimating" around that much and would also need to go through the attic. Already have gas hot water heater and gas log fireplace and outside grill. Possibly a little cheaper since gas lines are already run. Will definitely look into this.
