Berlin, Fujifilm X-T2 with 10-24mm f/4 and X-Pro2 with the 56mm f/1.2

I have both, and yes the X-T2 is newer, has basily the same sensor, has more features and so on ... in short the x-t2 is maybe slightly the better camera, BUT I enjoy shooting the X-Pro 2 way more. I cant really tell you why but its just more fun ... for me at least. Not saying the X-T is not being used, I mainly use it for street and traveling, but most of my portrait or people stuff I enjoy more with my X-Pro2.

Personaly I would go for the 56mm f/1.2. If you have the funds. Not saying that the 50mm will be a bad lense, but... f/1.2

X-Pro 2 / 35mm f/2

Great job and good model. Now you should feather the light to light the rest of her body instead just her face.

Took my X-T1 on a morning walk with 18/2. There is something about X-Trans II, which the new III doesn't have...

Not sure if these count as street photography but let's give it a try

I second that.
But if I could only have one, I would probably go for the X-Pro 2. Since I tend to shoot more Street and Portrait I woulndt necessarily say the camera is better, just fits me better. There is something about the X-Pro 2 I really like. The feel, the looks. As a travel and landscape or basiclly anything else, the X-T2 is probably the go to camera.

After having both the X-T2 and X-Pro2 for a few months, I need to update my answer. The X-Pro2 is a fantastic camera and works great for my preferred shooting. The X-T2 does seem more versatile and easier to handle when using zooms. If I could only have one, I think I would recommend and choose the X-T2 simply for the versatility. For landscape work, the movable LCD is fantastic and the AF is a bit better for tracking nature or sports.
