Nice shots ! Great colors there !
Yeah, compared to the tamron/sigma 150-600, i find the nikon to be sharpest wide open, with the best VR.
AF wise, its on par.
The only disappointing thing is when paired with the tc14iii, I have to stop down quite a bit for anything usable. (The sigma 156s with TC performs better then the nikon 200-500 + tc14iii in this area)
You can't really bring the f-stop down much further beyond F8 since the DLSR's AF can't work beyond F5.6 for older cameras to F8 like D4/D810 eg. So to use teleconverters with zooms that are already at F5.6 or F8 unless newer models of DSLR can work AF thru smaller aperture.
