Hi end gas ranges will beat a good electric kettle in the USA. (kettle 7min, range <6 min). My wife picked up a used thermidor this last summer and it beats any kettle we’ve had in the USA so far by at least a minute. That said, the kettle is more convenient overall (auto shutoff, auto start, pour from same container), so we end up using it.
In the other hand the US kettle beat the crap out of our old gas range, and even the good range is not nearly as fast as a crappy electric kettle in germany, which clocks in at 4 min.
Source: have a 110V kettle and a gas cooktop with very large burners, still use the aforementioned trick.
