I have an induction stove. I can point a liter of water in right about a minute. I have not timed it with a stopwatch, but it is seriously fast.

Cheap gas is superior in speed to cheap electric, but at the midrange their differences basically disappear.

One thing that Gas will always have over electric though is availability.

If the power goes out in a blizzard you can usually still light your stove for emergency heat and cook food. Not so with electric.
