I know that ultimately it does get driven by purchase cost otherwise there is no way to use!
As an initial pass it may be easier to consider the best way to achieve a certain focal length.
I did this before purchasing my 400mm f2.8 two years ago. I wanted to get to 600/800mm f5.6 whilst only considering the Nikon 200 f2.0, 300 f2.8, 400 f2.8 and Sigma 300-800 f5.6 zoom. The most effective cost solution was to get the Nikon 400mm f2.8, I think that the Nikon 200mm f2.0 is a great contender but using a x3 converter to get to 600mm was I thought pushing the envelope to its limit. The Kenko DG300 Plus x3 converter that I have is OK but its results when compared with images from the prime lens look distinctly soft.
The whole situation is made more complex by the D4 and D800 being able to use f8 max aperture and still be able to AF, with other cameras this is limited to f5.6
