A pity the RAFs of these cameras are so awkward to process. I prefer the S5 over the S3 because it is (a little) less weird and can use add-ons from the D200 etc.
I must admit the menu setup of the Fuji S3 Pro is a challenge
It also reminds me of the small Fuji E900 menu (awkward as well) But if you get used to it, it's logical. The Fuji S5 is more robust with the Nikon D200 as a basis. And obviously very durable, a lot of these camera's are still working. The menu's in the S5 are perhaps more complicated.
But the reward is the output of these camera's with a RAF in the wide RAW setting (or the 400% in the S5) to trigger these great RAWS in 24.4 MB. Adobe Camera Raw can handle these files perfectly nowadays. With the selection of sRGB and 'Best Quality' (12 MB).
It's back to basics with these camera's without high ISO possiblities and image stabilisation, but luckily they take all Nikon F lenses.
