Very much not the case for me, with a (fairly good) US electric kettle and a natural gas range. They're comparable, speed-wise, for smaller quantities, and if I need to boil more than a liter or so, the stovetop is a lot faster. Elsewhere in the thread voltage difference are brought up—that's probably what does it, typical US wall service is far lower-voltage than in Europe. That, and I've definitely had electric ranges in the US that were incredibly slow to boil water, so that might be a factor. Gas, though? At least as fast, depending on the quantity. (I hear induction electric is even faster, but have only used those a very little bit at a couple AirBnBs, so don't really know, first-hand)
