@Cerberus Electric does that too. Anecdotally, basically every gas stove I've boiled water on was noticeably slower than the electric stoves I've had in my apartments, and those aren't high-end stoves.
@Cerberus Like I said, if you have a really fancy one, it can compete (though it'll be throwing that much more heat into your kitchen). But generally if you get a gas stove and an electric stove in a similar cheap-ish price range, like you tend to in apartments, the electric will be way way way hotter at max.
Let me try one more time. If you get a typical gas stove, and a typical electric stove, in similar price ranges, and use the largest burner on both of them to boil the same amount of water, I can basically guarantee you that the electric stove will do it faster.
Okay, I know there are variables. What I'm saying is, with the stove that you will actually have in practice, the gas heat output is lower than the electric heat output.
You're not going to be standing around in your kitchen and say, oh, this gas stove would have the same heat output as my electric stove if only the energy density of the natural gas were higher, and my gas line had higher pressure, and the burner were bigger.
Your gas stove is just going to not boil water as fast.
