AF 105mm f/2.8D is the older version, the current version is AFS 105mm f/2.8G VR. In macro world most use manual focus when you get really near to the 1:1. I am attempting 1.7:1 this dive trip with AFS 105mm f/2.8G VR and TC-17EII, and somethings with TC-14EII for 1.4:1.
My opinion between the 2 versions: similarly sharp, AFS faster AF (which sometimes can be a liability when ambient illumination level is low), and AFS better OOF bokeh. AFS 105 is likely to be more acceptable than AFD 105 when used as a portrait lens.
