I have had several of each, I prefer the BO for hunting, since it is trailer hitch tough and also seems to hold most arrows a little better, particularly if you cant the bow. I prefer the Golden Key rests with dual bearing support (Rover, PP) for 3D because of the adjustibility for going back and forth between arrows, tuning etc..., though the Bo works just as well, it doesn't have all the training wheels the PP has, like nice scares, and screw adjusts. The PP is better than the rover if you want to adjust nock height at the rest. I prefer the Muzzy ZE when shooting 5" fletch and carbons, which can happen in certain classes or hunting styles.

All this advice assumes a release.
