Gas does indeed heat quicker than electric, so you might save 2 minutes out of 30. Big deal. In other respects it’s quite similar, with one important exception: a gas stove cannot be turned down as far as an electric one.
You can do a lot of braises - fry stuff for a while, then add water/wine/stock and simmer on low heat. You can’t do that on a gas stove. Turning it right down until it’s just about to snuff out results in a small but still-hot flame. The pot will be at a rolling boil, which may not what You want.
Plus, sometimes, gas has to be delivered in bottles, and is more expensive than electricity.
In addition, electric stove can be used of any cooking utensils.
