As you have seen in the 100 % crops from the sharpness test, the Nikkor produces warm colors. The Tamron is more natural with a slight hint of warm colors. The contrast on both lenses is very good.
Flares and Ghosting
The Nikkor is more prone to flares. You see them more or less in every picture with a strong light source directly ahead or towards the edges of the frame. Here I want to show you 2 extreme examples. The Tamron does very well here. I was not able to produce major flares with it. Ghosting is not an issue at both lenses.
Both lenses do very well here. I did not notice any C/A on my test shots.
Field of view and Vignetting
In this regard the Tamron is a bit wider at 24 mm than the Nikkor. The reason may be the distortion of the lenses. At 35 mm, 50 mm and 70 mm the field of view is similar. Here you see an example at 24mm. You can identify the pictures by the Flares (Nikkor) and the heavier vignetting (Tamron). The vignetting itself is visible on both lenses at F2.8 but gets better when stopping down. It disappears completely with the Nikkor lens at around F5.6 to F8, while with the Tamron, there is always a certain amount visible.
The Bokeh from the Nikkor and the Tamron is very pleasing and creamy. The only drawback with the Tamron is the onion ring bokeh which is slightly visible at blurred light sources.
Here you see bokeh samples of the Nikkor at 70 mm and 24 mm at various apertures.

Both 24-70 lenses offer a really great overall performance. The Nikkor is a bit ahead in terms of image and build quality but the Tamron offers the advantage of the lower price, the VR system, the more modern coatings (Flares) and the more precise zoom- and focus-ring. As I said in my hands-on review of the Nikkor it depends on your own style and how you like to shoot to pick the right lens for you. Both lenses are really recommendable but I think the Tamron is the more versatile choice and the slightly better image quality does not justify the higher price of the Nikkor.
