I absolutely love my Nikon 60 mm macro. While it is true you have to be closer to get comparable magnification compared to the 105, it has a better edge to edge flatness of field, less edge aberration and is capable of superior sharpness IMO. My opinion is based upon side-by-side comparisons for imaging of mammalian skulls. I have used it for macro imaging of live subjects capable of movement and have never felt exceptionally hindered by the need to be slightly closer.
