Complex carbohydrates. Body can convert these to energy easier than protein or fat and the energy is released evenly and over a longer time span than simple carbs such as sugar.

All these answers are correct, but energy usage is variable. For example, under starvation, gram for gram, fat will give you more energy. If you are well-fed however, fat will just be stored in adopocytes (fat cells). The fastest digested energy source in a well-fed individual is carbs, that's why we use them as fuel during endurance athletics. The best carbs are simple sugars or disaccharides, not ie starch from potato or bread.

What is "quality" of energy? Do you mean "quantity"? If so, then fat has the highest quantity of energy per gram (9 kCal/gram); carbohydrates and proteins are 4 kCal/g. Alcohol is 7 kCal/g
