I went another road for the paid shots, went and got myself a Nikon D500 and I did compared both the X-T2 and D500 and in term of AF speed, 3D tracking and buffer, the X-T2 while being superior to the X-T1 is still lacking compared to the D500.
The X-T3 might close the gap even further but I tend to use the right tool for the right job.
Don't get me wrong, I still love my X-T1, very much so, the shooting experience with the Fuji camera is still far above what I feel from my Nikon gear. Now if I am being paid, I will take my Nikon gear with me, if I am there for my own pleasure, that's where the Fuji comes in. My X-T-1 never leaves my daily bag with either of the 35mm lens on it or 27mm when I want the lowest profile.
