Gas has an advantage against traditional stoves with a resistive element that heats up from electricity, that you place the pan/pot on. It has a disadvantage against modern inductive stoves, where there is a coil in the stove that directly inductively heats the pan/pot.

The only disadvantage is that you need to use a pan/pot with a large ferrous bottom for best effect, but it's well worth it. Lag from changing heating setting is similar to gas, but the big advantage (aside from safety) is that the stovetop is typically just a large panel of glass. Super easy and nice to keep clean.
