Ethanol should not be compared on a straight octane rating either. Even "shitty" e85 from a pump still out performs most high octane fuels out there on high boosted applications like evos. The cooling properties to keep cylinder temps down are huge. Ethanol is awesome for anti detonation properties, so its not really comparable. Most shops will vote even crappy e85 all day long over most any race gas as its just better (assuming you don't get stuck with e50, but e70 is still great stuff) and its way more convenient to get as its at the gas station.
