How would you determine the most efficient fuel?

I have experimented two fuels: kerosene and hexamine with a calorimeter to see how much energy the water absorbs and how much fuel is used. Therefore the heat efficiency can be calculated by energy absorbed by water/fuel used x 100. So how would i calculate which of the two is better? Is it the one with the higher percentage?

The feul that yields the most energy without spending too much of the feul. Think of cars. The car that is most efficient is the one that maximizes the number of miles per gallon.
