Silkypix is worth serious consideration. I am now using it as my preferred raw software with both a Pentax K1, where it is pretty much essential with pixel shifted files, and a Fuji GFX 50s.
You have to work through the cluttered non-intuitive interface, but with both these cameras, different as the are, it is far superior to lightroom in my opinion. With GFX files, the decoded raws have less noise, and better colour ( P1, or Film Simulation, Provia for the best reds and to adjust the very slightly cyan cast to some GFX file skies). Just reduce sharpening from the default 30 to around 15-18 or so. With Pentax pixel shift files, you simply cannot use Lightroom on a shifted file, but Silkypix understands subject movement - say, a waterfall - and for moving elements of a scene, will compensate appropriately.
Silly name it may have, but it does a good job
