Best shooting I get are with peep sights. My FN 49 sights are great and the rifle is a hoot to shoot. Very easy recoil which helps with the sight recovery too. Second is my M1 Garand with windage and elevation adjustments. My No4's and 5's are comfortable sights for my old eyes even if I have to use a little Kentucky windage. Mind you any target beyond 200 yards is pretty fuzzy no matter what sight I use.
