This isn't a function of fuel, it's a function of output, which varies model-by-model. I have an electric stove/hob in my flat in London, and it takes -- no joke -- well over 30 minutes to boil two litres of water.

Conversely, my last house in the US before moving to the UK had a 25,000 BTU gas burner which was so hot that you could barely use it. It boiled water extremely quickly, and it was great for seasoning cast iron because of how quickly it would reach temperature and polymerise the oil. The whole setup was also easy to clean, as pretty much the entire thing came apart. Sure, not quite as easy as a glass top, but it also wouldn't get scratched all to hell by sliding my cast iron around.
