To me the top 3 advantages of the OEC are, first you have instant access to the visualization, there is no post-processing. Second I would put the fact that you can use it outside the lab, there is no need for an optical table. And last but certainly not least, you can build your own instrument and adapt it to your needs as they evolve.
