FT or Fermentation? - Best route from syngas to ethanol

In the process where algae are gasified to produce syngas, you have two methods by which to produce ethanol - either FT it, or ferment it...

Both have been attempted from what I hear...but which of the two is better - esp from a cost perspective?
