I had always preferred gas for cooking because of the ease of changing temperatures quickly, which is especially useful when making certain sauces, etc. And I've always found that an electric oven produces a more even heat for baking.
But now that I've been living with a gas cooktop again for the past couple of years, it's making me nervous. I have found on more than one occasion that I have inadvertantly turned on burners, but not to the extent where they have lighted, apparently just by rubbing along the controls while doing other things at/near the stove. I'm not concerned for a fire hazard so much as that the fumes are a big worry because I have birds. So now I am double checking all the time.
As for cooking with a wok - yes, the heat produced by an electric stovetop is inadequate. But so is the heat produced by a gas one, just to a lesser degree. The only way you're going to get enough heat from a gas cooktop for proper wok cooking is to buy a stove with a special high intensity heat burner, and those are super expensive.
A better (and cheap) option is to buy one of those metal gas cookers that people buy for camping or to deep fry turkeys. Obviously, you then have to use your wok outdoors, but it will do the trick.
ETA: When making sauces on an electric cooktop, I just got into the habit of lifting the saucepan a little from the heat when I had to reduce the temperature quickly.
