I have used the X-E1, 2 and now the X-T1. To me the files are not soft, however it you don't have a good raw conversion process, then you might be fooled as many of the raw converters still seem to have issues getting the best from the files.
On the issue of noise reduction, on a raw file I don't believe that you have noise reduction in effect, as it's a raw file. Yes, 0 is standard but I believe that applies to jpgs. I may be wrong on that, but it would be the first raw file I have seen that is have any noise reduction applied in camera.
Raw converters: From what I have found.
Iridient and Photo Ninja seem to have the best all round detail/raw conversion. However both have very limited tool sets, Iridient almost nothing. But these two converters do a great job on pulling the max. from the files.
LR with version 5.4 is better, but still have a bit of trouble with a lot of green and finer details on rocks i.e. patterns, lichens etc. I have found in LR to use minimum sharpening in LR and then move to Focus Magic as it does a great job on the files.
Capture One at 7.2.1 did get much better, however it's still a bit troublesome in certain images. Again, I will tend to use nominal sharpening in Capture One, but use the excellent tool set to work on other issues. Then move to Focus Magic for the final sharpening, or Topaz's deconvolution tool. Both do great on these files.
Net, to me the Fuji files can do a great job, and hold a tremendous amount of detail, you just have to work with them a bit and find a raw converter that works for you.
I don't use jpgs from the camera very often, however I always capture a raw and fine jpg as the capturing a jpg allows you to zoom in to a greater amount on playback.
The Olympus EM Series also get great marks, see the review by K Raber on both of these cameras on this site.
To me the greatest assest Fuji has are their lenses as all seem to just work great and are a perfect compliment to all the X cameras.
