The smell, worry about it being left on. I've got kids, they like to cook, I'm sure they'd be capable of dealing with a gas cooktop (we've got a bunsen burner for science stuff) but it's just nice not having that.

We don't get gas pipeline connections here, we get bottles that a company comes and replaces.

Compared to gas, I find induction just as responsive, more powerful on the highest setting. A nice feature is the auto heat which gives it more power until the pan is at the target level then reduces. I also think (but not sure) that the lowest level is far cooler than the lowest gas setting was, making it easier to use for baking - melting butter, chocolate, things that require gentle warming.

So, as I say, other than the specific flames around a wok, it's better overall. I do have an induction wok, it's not as good. It's fine though, I wouldn't trade or bother with a separate gas cooktop just for that.

Regarding kids + induction vs gas. I think it is much easier for kids to harm themselves in case of induction. They surely have learned that fire burns, thus they are conditioned to avoid touching fire, whereas induction is different. My two cents.
