This has all been said on previous threads but it is a good question. I have both and have shot with them both extensively. I loved the XT-2 and posted 5000 images with it on my travels the past couple of years. But I will never shoot it again. Why?
Because I love the XH-1 so much more. Image quality? IQ encompasses a lot of elements and one of those elements is the ability to hold the camera completely still. 95% of IQ and sharpness complaints about cameras and lenses are really caused by camera movement. The IBIS of the XH-1 is a game-changer for Fuji and it adds tremendous capability, so it rules with this amazing Fuji glass. I will never shoot a camera again without IBIS. It is that good.
White balance? Interesting. I don't care about color temp because I shoot RAW and always play with it in post. But that said, I have noticed over the past year that Fuji seems to be getting better with nailing WB and that is probably all firmware related.
But yes, I can't prove it but I feel the XH-1 is just nailing WB in a wide variety of situations where before auto WB would miss. I can't explain it. I tweak the color temp less in LR now.
The XH-1 feels better in the hands and I love the big grip.
The EVF is amazing and I can't believe it is not given more attention.
The build of the XH-1 is far superior to that of any other Fuji camera by a large factor. It has to be the most rugged body out there. Can't prove it.
I really like the top LCD. Didn't think I would. The Fuji ergo is still the same. The EC dial is is not a factor. It is really still there and actually better using the wheel.
IBIS is better than OIS as a stand-alone comparison (I think -- I can't prove it). Furthermore, IBIS added to OIS is greater than just pure OIS on the XT-2. The equation reads: IBIS + OIS > OIS.
Very generally and relatively speaking (and I can't prove this -- I just feel it from vast experience using both cameras), IBIS with the Brick, 90 or 16, for example, provides more stability than OIS with the XT-1 and say, the 10-24, 18-55, 55-200, or 80. The 100-400? I'm not sure because there is nothing to compare it to with non-OIS lenses and the OIS on the 100-400 is amazing. But yes, IBIS is fantastic, not matter how you try to explain it. It adds something to OIS lenses and for non-OIS lenses, it turns them into beasts.
Is AF better with the XH-1? Yes. Absolutely.
Better high ISO? Anyone who says so will get flamed. There was a thread on that early on and the OP was ridiculed and run out of town by the angry Sony and Canikon mobs who were trying to convince everyone that the XH-1 was a mistake because it had the same sensor as the "old" XT-2. Yes, we all know it's the same sensor and that the 2nd processor is just for the IBIS mechanism - not for the exposure work. That OP on that thread was suggesting that he noticed a slight improvement in post. The LR sliders that adjust the tone curve seemed to have a bit more latitude. I agree. Don't know how Fuji did it -- probably software related than may or may not be added to the XT-2 in a firmware update. But I see it with the XH-1 because I have handled 5000 XH-1 images in LR in post. But I don't want to argue this forcefully because I can't prove it by posting images (which of course is the immediate demand of all critics) and I will get crucified, stoned, tarred and feathered and ridiculed by the great unwashed and angry mobs who hate on the XH-1.
The XH-1 is a much better camera in my opinion than the XT-2. Is it worth the extra 300 bucks? Of course. That is a no-brainer.
