I have actually. I have my X1D, I had the GFX for 15 minutes to play with at B&H the other day. I did not have a card with me to save the Fuji files onto. One thing to keep in mind is that Hasselblad will be releasing new firmware in the next couple weeks to add functionality to the X1D to bring it closer in line with the Fuji specs. The two cameras are also aimed at two different segments of the medium format market, in my opinion. Fuji has made a medium format camera, that is mirrorless. While Hasselblad has made a mirrorless camera that is medium format, if that makes sense to people. Hasselblad has the H line of cameras, so they wanted to make the smallest, lightest, most compact camera possible. Fuji had no medium format camera before, so they made a larger camera with much larger lenses, they are BIG, but light. So it's kind of hard to compare them as apples to apples. Fuji also has way more past experience with mirrorless cameras, so they have a head start with some of the functionality. I really couldn't tell the difference between the two EVF's. I didn't have them side by side, but I think they are about the same. The benefit of the Fuji is that you can upgrade it easily in the future. Right now the biggest difference that I saw was the blackout time between frames. The Fuji was quicker to come back, and when shooting a sequence the hasselblad stays dark because of the leaf shutter, while the Fuji doesn't, but the Fuji has this weird slow motion looking thing going on. The leaf shutter is clearly a trade off, but for a lot of photographers, especially current Hasselblad users, they will prefer that. It's not an action camera, so most people aren't buying it to shoot sequences.
