Depends on which efficiencies are important. Aren't you taking about sun etc. -> biomass? Whereas biomass -> ethanol appears to be a lot more important, and starting from simpler sugars and starch is a lot easier than cellulose, wherever the latter comes from. That also has a lot to do with the upfront capital costs you decry.
