I've purchased Bibble pro around version 4.3 or so. It's my primary PP tool now. I use it for raw conversion, wb/curves/exposure/sharpness/noise adjustments, highlight recovery, shadow fill-in, crop, rotate, print etc. That sort of thing. That's pretty much what I do to images. Very rarely I resort to The GIMP for actually editing things in or out or doing fancy stuff.
I love this software, despite occasional stability problems (they tend to add features faster than they can squash bugs) and think it's an absolute steal for what it does. It incorporates PTlens distortion correction, Noise Ninja and now Perfectly Clear, and runs on Linux, Mac (both kinds!) and Windows.
Which brings me to the point
I haven't been able to improve an image with PerfClear yet. They always end up overly vivid and strangely tinted. Gotta sort that out, your tiger certainly indicates that it can and does work.
(In case the above reads like an ad, I have no affiliation. Just a happy customer
