It depends on you... According to you, the Sigma focusses closer. How much the FOV will change while focussing closer is an unknown factor, but will get smaller flowers bigger in the image.
The depth of focus choice is also up to you. At the same distance, the Nikon is capable of a much more shallow DOF. Its maximum aperture is 56.7mm, from the Sigma 17.9mm. So the Nikon will give you more artistic freedom, when needed.
So that is your choice, between these two unlikely candidates. If you want to get closer, the Sigma offers that. If you want to have the possibility to get a more shallow depth of focus, the Nikon offers that.
Of course, the Nikon with a Sigma 70mm f2.8 macro lens gives more depth of focus range, and goes closer than the DP3.
