The 2 biggest differences would be flavor and smoke point. Butter will burn and smoke long before olive oll will. If you are frying with butter, keep the heat low. Foe Sauces and Gravies, especially those with milk in them, butter usually works better. Sauces with a tomato base would work best with olive oil. It is also great on foods you grill, and in marinades that include vinegar, or with citrus and garlic.
"Cooking oil" is made from either soybeans, canola or corn. Olive oil is pressed from olives. Olive oil is supposed to have a lot of monounsaturated fats and different fatty acids that "cooking oil" doesn't, so olive oil's supposed to be better for you than "cooking oil." (I put cooking oil in quotes because there are several different oils that fall under that category--canola, corn, soy, peanut, cottonseed...even olive!) Then again, olive oil isn't a universal oil
