Is post production sharpening necessary with D800E?

Going cross-eyed here, bud, and that image of yours is as tough as it gets

It's going to be a subjective compromise because none is perfect: in this case I probably prefer the 'Reilly' version best because LR4's appears a touch too soft to me.  If there were one between the two I'd probably choose it.  Odell's is way over the top, as is the one with my settings for this crop.
