Some range ovens offer a baking drawer, which enables a person to use the main oven to roast or broil, and the baking drawer for cookies, breads, pies, etc. This offers a lot of freedom, allowing for simultaneous cooking.
Most single wall ovens have a volume of 3.1 cubic-feet, whereas most range ovens have a volume of between 4.2 and 4.8 cubic feet, generally. If you're a casual cook preparing simple meals a few times a week, the standard smaller oven is probably just fine for you. If you're an avid baker, or if you regularly cook for large groups of people, you might consider a larger oven or dual ovens. The following chart is a good rule of thumb. Generally, larger ovens will be more expensive. You obviously also need the corresponding amount of space in your kitchen.
