The only way to know what works is to try it on your engine.
Some fuels have have a faster burn speed than others,some have more btu's per gallon than others. Octane is just an indicator of a fuel's resistance to detonation and does not really indicate a good fuel.
I tested two different brands of pump premium and saw major hp and torque differences on my dyno. The local Citgo was better than the Sunoco around here.
It depends on many factors,not just compression ratio.
