Baloney. ime, induction is much faster than gas and flattops are as well (both electric and gas). Most people using gas, however, have residential gas ring burners, which actually suck in myriad ways, despite the accepted meme on this forum that gas is always better. I can assure you that gas burners boil water far slower than my electric flattop unless you have some of the very top end residential gas stoves. They also completely suck for setting dishes to cook at a slow simmer. Then there's the issue of the heat ring with gas; an issue that isn't one with an electric flattop.
I'm so tired of people jumping on the gas cooktop bandwagon as if it is the next coming. It's bullshit. A flattop, electric or gas, is superior in so many ways. And let's face it, very few in here have a gas flattop in their home kitchen.
Edit: And for those home cooks wanting high btu's for wok cooking, a high output LP ring burner is the best solution.
