Discov3ry VS direct ink writing (DIW)

Does anyone know for paste extrusion-based 3D printing, what are the advantages and disadvantages of using Discov3ry than using DIW method?
Compared with DIW where the syringe locates directly on top of the nozzle, the ink in Discov3ry undergoes a long feeding tube before reaching the printhead. Also, the volume of the syringe is only 60 ml. Have some ink travelling trapped halfway seems not a good idea.
What do u think of this issue?
