The C1Pro is very comprehensive SW and is oriented for professional use. Not so easy to learn as LR. Only basic editing need min. one month studies. But the results - when you really learn customizing and processing in C1Pro - are on very high level, especially the RAF files.
I´m C1Pro user since version 4 and I was simultaneously user LR 4, 5, 6 for other systems as Fuji. From my experience is C1Pro the best RAF editor in Windows. Specially for skin tones, excellent detail resolution and w/o watercolor effect.... and the editing/masking in up to 16 layers pro image is awesome.
