A scoped sight on a rifle is not necessarily "just better". It might depend on the kind of hunting you do when a quick-handling rifle with a peep sight is "just better" than a rifle with glass, no matter how low-powered the scope might be. Much of my big game hunting is for whitetails in the heavy cover a Michigan cedar swamp affords, offering relatively few opportunities for shots approaching 100 yards or so. I have four rifles I use for this kind of hunting habitat, all equipped with a Williams "FoolProof" aperture sight: an early Remington Model 760, chambered in .30-06 Springfield; a Winchester Model 94, chambered in .30-30 Winchester; a Winchester Model 1886 "Extra-Light Weight", chambered in .45-70 Government and a Savage Model 99, chambered in .358 Winchester.
I use scoped rifles for the majority of my hunting but in my opinion, based on my experience, there are a lot of times when an iron-sighted rifle, especially one with a peep sight, is just better than one wearing a scope.
