The 60mm is an optically fine lens and a nice short telephoto for portrait/general use. The 80mm is generally better for insect type Macro shots as it gives you a longer working distance which is better for getting a bit more light around the subject and even when used with tubes it can still give an acceptable working distance. The 60mm when used with tubes can very easily shield light from the subject with its own shadow as the working distance is that much closer.
Optically the 80mm is reckoned to be the sharpest lens in the Fuji-X range and is a tad sharper that the excellent 90mm, since getting my 80mm I have not used my 90mm as the 80mm is also Excellent as a normal medium focal length telephoto lens and of coarse its a stabilized lens where the others are not.
Just my opinions on having and using all three of these lenses.
