Its better for boosted cars or cars with high compression engines since it resists detonation better. Hence the reason why cars running lots of boost need to run race fuel or e85 and are able to make more power. Yes if you don't have the high compression or boost you will lose mileage due to the lower energy content in the higher ethanol fuels.
