Dude, I own the company, not an employee!
You might think there is no difference but I'll let all the other commenters do the taking on that one, except for the post where I mentioned that the resolution is, of course, amazing with 102 mp on tap, but all the other things that Fuji have put into the camera add up to make this GFX a great experience to shoot with. That should really be the takeaway with this camera, the juicy sensor is just a (really nice) bonus.
As far as IQ differences goes there is not that much save the extra colour/resolution in the 102mp sensor and as I've said before the 50r is a good way to dip your toe into the water of shooting digital medium format. You can even adapt some of the 135mm lenses with good results.
I'm not one for pixel peeping in general images but part of my work involves making sure the images will hold up full scale so I'm more often in a 300% checking things out before I let it go to the client. Still, quite amusing to zoom into an image by 400% and see a sharp detailed result.
Also no need for high megapixel imagery for a billboard as the viewing distance if so far and they are printed at a very low resolution, something like 15dpi I think. Large scale commercial photography that get put into high street shops and hotels or airports do however get printed at higher resolution, I shoot a fair amount of that each year, so having more resolution helps there for sure. Oh and we have no Sony glass as they don't make any decent lenses for video work & the mount is an E-mount anyway. But I'm sure you are well versed in all of the different video mounts Alan...
Anyway is the new A7r4 capable or outputting 4:2:2? or 10bit? or 4k/60? or HLG? No? Really, but Sony said it was 'professional video'...
But yea, as you say, it's not your business or money because if it was you might want to figure out these things before you comment on what's best for the use case. Eh?
Anyone else find it really interesting that some people refer to the same sensor that's fitted in the Pentax 645d as well as the Hasselblad H6D as 'mini medium format' suddenly when referencing Fuji's camera & never before thought about it when mentioning the others who use the same size. Gota love that.
I've been calling out mini medium format since the beginning 
it's interesting because if you prefer the squarish look, it's not really that mini, and the difference can be big, but if you prefer wider, then it is mini indeed. I tend to gravitate more squarish for human subjects, wider for landscapes.
I'm a little underwhelmed with the R4, it feels like half a typical body release from sony, and they should have waited a year or two for a more meaningful update. No doubt it looks to be a fantastic camera, but it's not that big of an update depending at what you're looking at. On a pixel level, it's huge, everything else.... seems like all it is, is a new sensor, and for body refinements, the A7R5 will be the way to go. Guessing based on R2-> R3, rehashed the sensor, but big moves on the body + AF, absolutely huge.
they roll out the sensor first, then roll out usability second, so it'll be a while before I update, sorry for the rant.
