Gas: Cheap and easy. Visual and intutive. Better Feng Shui: "Natural" cooking over an open flame.
Electric: Faster, cleaner, safer, cooler. As a class there are more electric stoves in this country than gas, yet there are fewer accidents with electric.
Studies have shown that a gas oven operating for 1 hour at 350*F (175*C) provides enough moisture, carbon dioxide, sufuric oxides, and nirtous oxides to be a detrimental to your health and should always be used with a window open or an exhaust fan running.
Similarly studies in the UK have shown that children who grow up in homes with gas cooking have TWICE the number of repspiratory ailments than those in homes with eletric coooking do.
In my area (in homes with gas cooking) one has to paint every 5+ years to cover and degrease the filth that comes out of a gas oven's vent, being byproducts of combustion and grease/dirt. Went to a home in Florida, all-elctric and no combustion source in the home. I asked how the popcorn-style ceiling (scores of hanging dingle-berries) was painted. Their response: The house is only 25 years old and the ceiling has never been painted. Why would you need to paint the ceiling? They asked.
From that time forward I paid attention and indeed electric cooking is MUCH cleaner. The few extra drachmas every month in energy cost is worth not having to wash walls, ceilings windows, floor and indeed EVERY other surface in the house.
I quickly went to an electric smooth-top (glass/ceran) in my upstairs kitchen and had both a standard-sized 30" (75cm) electric and smaller 20" (50cm) gas in the basment (entertaining) kitchen.
I was able to run the cables and pipes myself. (I seem to have a talent with pipe).
My current (rental) residence has a gas self-cleaner and it a marvelous Magic Chef (think Maytag). Still cant stand that gas surface burners heat the handles up on pots, heats up the room like crazy, and one has to breathe in those poisonous fumes when stirring.
Both types/enegy sources have their merits and disadvantages. It's what is most important to you that determines what is preferred. That, of course, and the availability of gas. Supe hot climates from what I have seen don't nomrally have gas cookers. Less of an issue now that "everyone" has cental air-condtioning in this country.
