Winner: Sigma 24-70/2.8 DG DN Art (Sony E)
Regarding minimum focus distance: The minimum focus distance of a lens is the smallest distance from the lens to the subject you want to be in focus; subjects closer than the lens' minimum focus distance will not be in focus. Whether or not this is important to you is up for you to decide, but some want to take close photos and videos and in those cases it's important to have a lens with a low minimum focus distance.
6. Lens Type Comparison
Both lenses are Zoom lenses, which means that you can choose both Sigma 24-70/2.8 DG DN Art (Sony E) or Tamron 70-180mm F2.8 Di III VXD if you're looking for that type of lens.

Prime lenses have a fixed focal length and cannot be zoomed, while zoom lenses have a focal length range and can be zoomed in to get closer to the subject. Prime lenses are usually lighter, cheaper and let in more light. Zoom lenses are more versatile but are more expensive since they require a more advanced lens design.
7. Filter Thread Comparison
The Sigma 24-70/2.8 DG DN Art (Sony E) feature a filter thread diameter of 82 mm while Tamron 70-180mm F2.8 Di III VXD feature a diameter of 67 mm. Depending on your current gear (like other lenses or filters) one of them might be favorable over the other.
Winner: Tied — It depends on your gear
Regarding filter thread diameter: The filter thread diameter is the size of which the lens is compatible with screw-on filters, such as CPL, ND or IR filters. If you have several lenses of a certain size, it might be a good idea to keep the same filter thread size to make sure your filters work on all your lenses. If not, then you may buy step up rings to adapt from a certain diameter to the filter thread diameter of your other lenses.
8. Stabilization Comparison
Neither Sigma 24-70/2.8 DG DN Art (Sony E) or Tamron 70-180mm F2.8 Di III VXD feature built-in image stabilization.

Do remember that lens stabilization is not required, but it may be suitable depending on your specific needs.
9. Autofocus Comparison
Both lenses have autofocus, which means that they're both great at focusing targets while taking photographs or filming video. Just remember, most cameras do not offer good autofocus while filming video.
Winner: Tied — both have this feature
Regarding autofocus: Lenses with autofocus help you focus when shooting pictures or video. If a lens only has manual focus it means that you have to focus manually by adjusting the focus wheel on the lens. Most cinema lenses do not use autofocus and are manual focus only.
