For what it's worth, pfstools is sponsored by the Max Planck Institute, who've done lots of HDRI-related research and presented many times at SIGGRAPH and Eurographics. pfstmo, specifically, is maintained by Grzegorz Krawczyk of MPI. The pfstmo homepage explains exactly which tone-mapping algorithms it implements, along with a convenient URL that provides more information about each technique
If you'd like to get a feel for what pfstmo's operators can produce, there's a comparative gallery here:
As far as I can tell, all of the operators that produced those images are available in pfstmo, except for Greg Ward's, which is probably available in the Radiance package (free for non-commercial use), if not in pfstmo. The gallery also links to a short paper which describes the parameters used to produce the images.
As for recommending pfstools to photographers, I guess that depends on whether they're comfortable with command-line tools and possibly building their own packages (pfstools is not available in MacPorts, for example). If they are, then the availability of high-quality gratis tools is always a good thing, right?
Kudos to MPI for making both their HDR research and their code freely available, by the way. It's a great set of resources for people interested in HDRI.
