I just bought the upgrade to PSP X7 Ultimate. I'm not sure about all the new features as I haven't had a chance to really use them yet, but have dabbled with Face Filter 3 (not as easy to use as Portrait Professional). The Clear thingy might be OK, too, but haven't really tried it.
I always open in Edit. For file management, I just use Windows Explorer--easy to drag & drop and create files for edited shots. I tried the Manage function when it first appeared (was that version X5 or X3?) but for my workflow, Windows Explorer just seemed easier.
If I'm just working with a couple of RAW files, I'll use PSP. But it's too slow compared to Lightroom 5 to handle 200 files from a single shoot, and LR allows a much greater range of adjustments to the RAW files before I export to JPG. But the re-touch work is always a PSP job. It's blemish tool, scratch removal, basic skin smoothing, noise control, and most importantly, it's sharpening tools are really quite useful. It clones well, too. Moreover, I like using it's resizing tool for web posting (and the accompanying jpg optimizer to squish the file size).
