Depends on the definition of stored; as in directly usable by the cell? Definately ATP is the best form of energy. However, as far as total energy gained per molecule via biochemical reactions:

E is a good answer, starch consists of thousands of glucose molecules. However, starch is poorly digestable, we lack a critical enzyme to break it down. Glucose can yield 30 ATP via glycolysis. Molecule for molecule, starch has more energy. By weight, glucose has more.
