I got talked into Portrait Professional with a gushing endorsement but very rarely use it. The pre-sets are awful and profoundly fake. If you must have it, zero EVERYTHING and add in very small doses of the many options.
With the volume of work I process, Portrait Professional is slow and cumbersome, I'm much quicker achieving superior results in Photoshop (plus a bit of Lightroom). For anyone with moderately advanced Photoshop skills, like so many of the plethora of plugins and add-ons, Portrait Professional is high on promise and light on delivery.
In my workflow, Portrait Professional is a destination of last resort for a particularly awkward subject.
