The electric one might heat a wee bit faster, but I'm a purist when it comes to fresh water when making tea. I would heat that 1 quart-plus in the electric kettle, then pour more than half out after filling my cup. My best use for it? To boil water in the basement when I had to do a thorough hot-water-and Oxyclean cleaning of my front-load washer.
I bought an OXO brushed stainless kettle
over a year ago and love it. It holds just over 1 1/2 quarts, which is still plenty if I'm making a big pitcher of brewed tea for ice tea. It's comfortable to handle, too. The lid removes completely, so I take it off each time I use the kettle so that the inside dries, even though it's stainless steel. Got it at BedBugs-andBeyond, too, so there's that 20% off coupon thing going for it.
If your stove is not a glass-top, you could consider a Revere kettle
. I had one for years, loved it, but when I got my glass-top stove it wasn't as efficient because the base of the kettle is a wee bit above the surface of the stovetop - the rim that holds the copper base to the stainless kettle won't let the base touch the surface for optimum heating. I gave the kettle to our daughter, who has a gas stove, and use it every time we go to visit our kids and stay with her.
