I use both. Stove top kettles are less efficient, but they have a few advantages over electric kettles. They: - work when power is unavailable (outages, camping, etc.) - are more or less indestructible - don't take up counter space I have one of those big 4L Zojirushi electric kettles that I keep plugged in for 8-10 hours a day. Sometimes I will use the stove top kettle for supplementary boiling water when people in my household are using the electric, or I don't want to start a reboil cycle or take too much at once.
