Gas or electric?

Do you prefer a gas or electric stove? Our oven is having issues. It is not cooking anything in a time frame that’s anywhere close to what the recipe predicts. At first I thought it was because the oven just wasn’t fully heated when I put the items in, but even now that I’ve confirmed that the oven reaches the correct temperature, it still doesn’t cook things properly. For instance, I put a chicken in the oven. According to the recipe, the top was supposed to be browned after 20 minutes; it’s been 60, and it’s still white as snow.

So now my question is this: would a gas oven at 400 degrees cook worse or differently than an electric oven at 400 degrees?

Thoughts?
