A gas cooktop will produce more heat than an induction cooktop, but I don't think a gas oven will produce any more heat than an electric oven. People get electric ovens because they "think" they will produce more even heat than a gas oven - but for the most part this isn't the case.

I've found two freestanding ranges that have double ovens: Jenn-Air Maytag This seems to be a good compromise, as I don't want the initial expense of double wall ovens with a separate cooktop in the counter. Our budget needs to be $2,000 or less for all our cooking needs (range, cooktop, oven, etc.) not counting ventilation. And we're talking stainless here. Do you have any experience with either of these ranges? Do you know of any that are slide-in, so that it has a nicer appearance? Or am I making a dire mistake in thinking this is a great way to go? Thanks!

I can only speak to the Bosch which I've had for about 8 months. I'm happy with the oven, in particular the adjustability down to 100 deg. Yes I'm fairly well-versed in food safety, but sometimes you just need a big warming drawer. The 10-pass broiler is hot and even. The cooling fan does run a lot, but I don't find it offending in either noise or heat output. Less enthused with the cooktop. While the wattage specs on the highest burner are good, you need cookware with approx 11.5" base to utilize it. Your standard 8qt tall stock pot only takes two rings and is therefore dreadfully slow to boil on any burner. On the other end of the spectrum the low is higher than I'm used to. The Schott Ceran is significantly more sensitive than my previous Frigidaire. I had chips within weeks of using it, more now, the silver pattern seems to clean off, and in general I find it poor quality. The paint on the knobs peeled off at first cleaning; fortunately Bosch was aware of the problem and sent me a new set which has help up thus far. Overall, there's a lot to like about the oven but enough to dislike about the cooktop to where I wouldn't recommend it. My #1 takeaway would be to look for a power burner that matches the diameter of your most used cookware, in my case a 12" skillet and 8qt tall stock pot.
