Electric Ovens Are Even
What goes for the stovetop goes opposite for the oven: For baking, roasting and broiling, electric makes for better results.
The best heat is even heat -- that's the way foods get cooked all the way through, and cooked the same amount all over. A gas oven typically has a single, centrally located heating element on the top and another on the bottom. This makes the oven hottest in the middle. If you put a whole pan of cupcakes in there, the ones at the edges are probably going to be less done than the ones in the middle.
With an electric oven, the heating elements typically wind back and forth all the way across the top and all the way across the bottom, meaning the heat is distributed much more uniformly throughout the space -- and the outer cupcakes get baked just as well as the inner ones.
