180 ED Nikkor vs modern 70-200 vs 135 Sigma ART?

I am considering a 100-200mm lens to boost my range while staying portable with the small ioptron tracker/travel tripod combo.

Any particular advantages of the modern lenses against the venerable 2.8/180 for astro (AIs or AFD)? It is consoderably lighter and far cheaper. Of course not f1.8 as the Sigma, but offers a very similar physical aperture. Question is how coma and vignetting are controlled wide open?
