My strong suggestion is get both Seriously both lenses are superb, and the 50-140/2.8 with 5 stops of OIS is must have lens if you doing portraits. Then the 90/2 and 56/1.2 APD I have all three, and I tend to use the 56 APD the most, while the 50-140/2.8 follows closely behind. The 90/2 tends to be a more specialty length 135mm.
I have many 70-200/2.8 zoom lenses, both Canon and Nikon and I would have to say the XF 50-140 is my favourite. Here are some sample shots immediately I bought the lens on the XPro 2
