Been spending a lot of time on here!
My experience over the years with Sigma lenses (both MF and AF) are that they are optically good but the build quality is often poor and they tend to break rather easily from normal use. First the surface markings wear off and then the moving parts start to break. Maybe the newer lenses are built better but I would never buy one to find out.
I would go for a gently used Nikkor over a new Sigma any day. Its value will also hold much better than a Sigma if you later decide to sell it.
