Both will do fine. If you are a person who likes sharpness over a big depth, there is no reason to look at an f2.8 zoom as you will not be using f2.8. If on the other hand at times you want a shallow depth of focus, you should not be looking at the 16-85mm.
That is the choice you will have to make... the Nikon has a longer tele range, the Sigma offers f2.8. Those two aspects will have a much bigger impact than a slight difference in sharpness somewhere.
