Yes, I know it's not technically just methane, but methane is its primary constituent.
"Fossil gas" is also probably a suitable term, but I like "fossil methane" because it gets that spooky chemical name benefit.
It's not about how long it takes, what matters is constant, even heat. Electric coil stoves turn on and off to regulate heat so you get crazy fluctuations.
Gas doesn't have that problem. Good induction stoves don't, either, but they're still hella expensive. And you need the right pots and pans or you will have a bad time.
There's a reason basically every restaurant in the world uses gas cooktops.
