My organization switched to using BlueBeam recently, about 18-24 months ago. It is easy to use the basic features, although the interface is intimidating at first. We distribute PDF's electronically, reviewers get a link to a BlueBeam review session where they mark up the PDF. At a 90% or final review for a large project we may have up to or more than 15 reviewers. Once one of them has commented that a particular note or detail is wrong, we don't need ten more identical comments on that same note.
The big advantage is adding structure to the review. The PM defines a time limit when the review session is created, and the session allows others to see all comments in real time, which avoids duplicate comments.
Some other advantages are that other files can be embedded in the review copy by commenters. So for example, if I need to update a project spec, I can find the updated text and attach it to the copy I am reviewing. Then our spec writer can copy that text, and edit it into the final document. This helps eliminate transcription errors.
