The 400 2.8 E has some truly horrible bokeh under a fair number of conditions, while being the sharpest lens I've ever had on my D800e. The 500 wasn't as sharp, but I don't recall any particular bokeh issues.
It's very subjective, but it is also very background and lighting dependent. I can achieve rubbish bokeh even from the best of bokeh lenses.

Well, you can get soft pics with the sharpest lenses too, but that doesn't mean the lenses aren't sharp--correct? Generally, quality of bokeh is judged by smooth transitions to out of focus areas. This transition is judged before, as well as after the focal plane. Being good in one, does not necessarily mean the lens is just as good in the other.
Sure, backlighting can have the effect of degrading bokeh, but the best bokeh glass will handle the same poor light conditions better than lesser bokeh glass.
Subjective--what the hell in life, besides mathematical theorems & other matters in the realm of science & math isn't subjective? Wine quality is subjective too, but we still detect and rate smoothness to surprising degrees.
Some people like the bokeh of the Russian Helios glass, but none would argue it produce smooth OOF transitions. jt
