Personally I suspect a lot of the diehard adherents to gas cooking haven't had a chance to cook with a modern glass top resistance or induction stove. IMO the difference has shrunk dramatically.

Water heaters too, electrics have improved and the operating cost difference is really not that big. Electric water heaters might also be extremely valuable for demand response.

When it comes to space heating in cold climates though, I don't really know what replaces natural gas. Probably air source heat pumps, but they are still maturing.
