I compare AP to Photoshop, not Lightroom. The RAW processing in AP is lacking but the photo editing features are right up there. While I use FastRawViewer for vetting my RAW files first I use Capture One Pro for RAW processing which is (one of) the best out there, plus it includes session/catalog management. When I need to "edit" an image I use AP; for example, to remove distracting elements. I'm also happy with AP for printing.
C1 with AP are an alternative to the LR and PS combination, but would like to see AP catch up with LR and C1 for RAW processing and also include session/catalog management.
