I mean, if you are looking at unventilated kitchens, you are going to get bad values cooking. Pretty much period. Yes, by products of burning gas are bad. But by products of cooking are already bad. Ventilate your kitchen.

Induction is also faster to boil water, easier to clean since it's just flat glass, and safer since an induction stove without a pot/pan stays room temperature (in fact, they usually can detect if a pot/pan is present and automatically turn themselves off)

Induction is also particularly nice for certain types of cooking because many induction stoves can be set to a specific temperature instead of just to a power level.

Even with very good ventilation, gas ranges will pollute your air to a surprising degree.
