I think wide open the Nokton has smoother bokeh than the Volna-9. I't just the OOF circles where Volna-9 excels. Both lenses have very smooth bokeh.
Actually to see how a regular 50mm lens compares to these two, bellow is a Pentacon 50mm f/1.8 at f/1.8:
You can see how busy it is and the OOF circles are much more pronounced. I don't think another 50's lens can beat the Volna-9 and the Nokton in smooth bokeh and OOF circles department. Of course these two are not the sharpest lenses wide open but this is not the point.
If you ask me which one is more pleasant to my eyes, it is the Nokton.
