Does biodiesel have higher EROI than ethanol?

I recall reading that biodiesel has high EROI (energy returned on energy input), and some data suggest these could be about 8:1, and it is also said that the EROI for ethanol is usually less than that for biodiesel, that is, if both are derived from the same feedstock...

I am wondering whether this is true for all feedstock? Is it true that for algae as well, algae ethanol would be having a lower EROI than would biodiesel?
