It's been pretty much said. Both lenses will give you nice images. I have the 60 and rented the 56 for a week. I decided not to buy the 56 as I don't do a lot of portraits or use that length as a walk around lens. I'm shooting with an X-T10.
The 56 is a bit sharper, but we're talking the difference between excellent and superb.
The 56 is the choice if you want manual focus. The throw on the 60 is stupidly long.
The 56 is faster.
The 56 focuses faster
The 60 is lighter and smaller.
The 60 focuses closer and with higher magnification.
The 60 is a lot less expensive.
For portraits, where super fast focusing isn't important, the 60 is fast enough, especially on the X-T1 or the X-T10.
The 56 has a different color cast. I prefer the 60 but YMMV.
The 56 is a specialty lens. It does what it does beautifully, but unless you are making a lot of portraits, it may not be worth the cost.
The 60 is exceptional at nothing but decent as a macro or portrait lens.
I shot my last set of portraits with a Voigtlander 75mm f/1.8 on manual focus. Since I use studio lights or manual flash, I'm shooting manual exposure anyway. As Fuji does manual focus aids so well, focusing is a non-issue for me. I only add this to say that there is no one best lens and that each lens offers a different rendering. The only way to really know what you like is to try each of them out.
