Lightroom is horrible with Xtrans files, whatever the settings you use. In the other hand, Capture One pro 8 is just awesome and I do not regret having bought it. I was first stage Lightroom user but today, even Nefs files are better with C1.
You guys are messed up with fuji color profiles. Those color profiles are only usefull with in camera jpeg. You choose the style you need for jpeg only.
At raw level, those profiles do not apply. Instead of that you have a file with a lot of room, very clear, who have nothing in common with Velvia, astia and so on. The only setting who is close to the raw file is Pro Neg with -1 shadow and - 1 highlights.
With capture one pro 8 you can apply a routine at the importation, Pre-sharpening, applied on the raw file. That give you a very very good file to work with, far better than LR.
To be clear, files was almost a deal breaker for me with the fuji system... until I found out how to proper decipher the raws and C1 helped me a lot in this venture
