What should I look for when buying a freestanding gas stove?

When shopping for a freestanding gas stove, check whether it is a "full gas" unit (gas burners and a gas oven) or a "hybrid/dual-fuel" unit (gas burners with an electric oven). Additionally, look for essential safety features like a Flame Failure Device (FFD), which automatically cuts off the gas supply if the flame accidentally blows out.
