The most popular ranges are still those with external heating coils, though smooth-top, hidden burners are gaining ground. External coils cost less, are easy and inexpensive to replace, heat faster, and tolerate warped pan bottoms. Smooth tops are more attractive, easier to clean and offer extra work space when not in use. Baked-on spills also require a special cleaner. Many of the features offered on electric ranges are available on gas ranges.
Gas is said to be the preferred heat source of serious cooks, because it offers better control.
While it's not true that gas burners heat faster, they can be adjusted quicker. In most cases, gas also costs less than electricity. Even with these advantages, gas ranges are not for everyone. They are almost always more expensive, and usually substantially so. And because gas appliances are more complicated, they often require more service and repair.
