It heats much faster and you tend not to have to worry about cool down and you have better immediate control over the heat. Also if your electric goes out you have a cooking source.

Of course there are cons with gas as well - mainly its well EXPLOSIVE. However the intelligensia trend to bring climate change into everything is annoying.

[edit: I just happened to get a magazine talking about induction stoves; apparently the temperature control is really good on these. However, with old fashioned electric stoves my comment still stands]
