Modern ones are well done, but old chimney based ones are a notorious problem.
Cooking is really the only thing where gas has real (e.g., not cost) advantages. Nobody says “this hot water just doesn’t feel right, I like it boiled by dragon’s breath”.
But a steak burned with gas is different than one burned with hot electric.
If you have the space/configuration for it, a really nice setup is an induction stove in the house, and then a gas-powered BBQ, so then you can cook outside for things that really call for gas. (Without any effect on your indoor air quality.)
