i would probably choose the D. it has an aperture ring which you will find useful when you use it with bellows
the D version also is fully mechanical apart from the D chip so servicing one yourself is possible with risking any damage to the electronics that need calibration from the factory.
the one thing I hated with my D was it just loves to attract dirt as there are several places where it can get into the objective.
i hated the 60mm for shooting bugs for the fact that getting too close would scare them, however the perspective does look lovely because the 105 has a tendency to make things look flat.
as for the G. tested it a lot throughout the years but just cannot justify buying one. i do not like the exposed front element as it might get tree sap when i shoot in the jungle. it does feel sharper but i really cannot tell both the D and F apart at macro distances.
the AF-D is also really noisy!
