Where it comes to fuels, Specific Energy and Energy Density are two major quantities deciding "how good" given fuel is. These are either given neglecting the oxidizer mass, or as a value combined with the oxidizer, as bipropellant.
What would be the corresponding quantity measuring efficiency of oxidizers? E.g. if the rocket uses the same amount of the same fuel, what measure would tell how its energy output to mass ratio changes when switching between LOX, nitrous oxide or peroxide - each in stochiometric ratio to the fixed amount of fuel? (...or some other method of measurement that yields a similar knowledge).
Some table with example values for various oxidizers would be nice too.
