Gas stoves employ an open flame while electric stoves utilise metal heating elements. Both have their benefits, gas stovetops are highly responsive, allowing you to move between heat levels quickly while electric ovens tend to have dry, even heat that's ideal for baking and roasting.

Gas

For people who are comfortable manipulating on open flame to their culinary advantage, gas is definitely a favourite.  Flames can be adjusted instantly which means more definitive cooking temperatures.  Cooks can char, grill, or toast directly on the stovetop and the open flame is also better for cooking with woks and skillets.  There is also no preheating required with gas and when turned off the response is nearly immediate.  They are also still usable in a power outage.  Gas is also less costly to operate so if you cook a lot, it means less energy consumption and a lower bill.

Gas stoves are harder to clean with their burner plates and crumb friendly spaces, which is one disadvantage.  Because they operate with an open flame, if not cooked on correctly they can use more energy.  They are also initially more expensive to purchase and install than electric units.

Electric

Glass-top electric cooktops start at a low price point and are a mainstream option for kitchens that aren’t outfitted with gas. They are easy-to-clean and with their sophisticated appearance, these cooktops complement many sleeker countertop designs. They also tend to maintain low heat much better than gas cooktops.

Electric stoves obviously require a power point close by to plug into and also don’t work in a power outage. 

If you’re really struggling to make up your mind whether gas or electric is best for you, consider this: most major appliance brands offer hybrid models now, such as ranges featuring a gas stove top with an electric oven. Sometimes you can have it all.
