They all differ, even within the same type.
No two of my J-3s draw the same, each has its own bokeh signature.
The early 1960s ones seem sharper at full bore than the latest black J-3s but the colour saturation in photos is better on these late made black J-3s.
But all that could be just from my sample of lenses.
The J-8s also vary, some are duds and not sharp, many are just average and some are equal to the finest Zeiss Sonnar f2 lenses, year of manufacture makes no difference to these variances .
If you do not need the speed and there is less chance to need shimming and want lower cost the J-8s are fine, as both lenses draw very similarly at the medium aperture settings.
