Boiling the kettle means I can make pasta and a sauce in about 12 minutes, boiling on the stove just adds tons of time. Given that the kettle is next to the stove it's simply self sabotaging not to use it, one button press.
Yeah huge difference if you have 240V mains. A 120V electric kettle is not much of a timesaver (though perhaps still worth something if it frees up a place on the cooktop that you need for something else).
