I've found induction cooktops do just as well as gas at boiling water. The frustrating thing about them right now is the market is immature, so the good ones cost well over $1000 per burner and the cheap ones are so much worse (lousy coil sizes and poor heating precision) they aren't worth using as anything more than a camping stove for tiny little pans where you don't need precision. It's like nobody in the industry wants to make these things good enough to actually replace the old technology, they just want to price gouge for all it's worth while it's still seen as the "expensive, hard to make, premium option".
