The Zero Image is the first "commercial" pinhole I ever owned, and before that, I only made a pinhole camera once on a photography course, so I can't compare it to other results, but it sure is a fantastic pinhole... The sharpness and detail captured are truly amazing, as well that it is able to cover 4x5 while just being 25 mm thick! (it is an extremely wide angle pinhole in this configuration, although one can add extension frames to lengthen the focal distance with this particular model).
