They have certain specific advantages, but they are actually slower.
This entirely depends on the stove. Consumer-lever stoves? Sure, definitely. Commercial stoves? Probably not. Commercial stoves put out 3-4x the BTUs of a high-end consumer stove, and usually can't be installed in a home because they require significant shielding around them (so you don't burn a building down) and a very high flow hood. The highest-end Wolf range has a single burner that has a maximum output of 10,000BTU, and costs a whopping $17,000; a fairly basic range top for a commercial kitchen has six burners that can all output 32,000BTU, and costs about $3700. For stir-frying specifically, you can get a single ring wok burners outputting 92,000-125,000BTU starting at about $700 for natural gas (and a helluva lot more if you use LP).
Unfortunately, I can't find a solid conversion between gas and induction stove capabilities.
Oh, and FWIW - if you live somewhere with an unstable power grid, a natural gas or LP stove will continue to function when the power is out, albeit you'll need to light it manually. We lose power fairly regularly due to storms--usually only a day at a time, but sometimes as long as 3-4 days--and it would be a real hassle to have all electric appliances when there's no power.
Oh my god, it's so bad.

It's like those stupid magnet bracelets and elbow wraps, only for your vagina. It's all woo.
