For whatever it might be worth, I purchased one of these for my Stevens 44 some time back. It is a #104 Schuetzen.
My intention was not for hunting applications but it could be used for that purpose without a lot of grief. I am not however a knob twiddler in the field. Within the viable range for that particular gun I would have it zeroed and know the intermediate POI elevations to include 25-50 yards beyond zero. I do not find the aperture difficult for finding the blade or target. My eyes are however not terribly successful with the original buckhorn sights.
My .02, FWIW
