It is hard to explain quality, as it is hard to exlain clarity. The quality difference in optcis has to be seen to understand. This is even more important in a hunting scope, when shooting is done in less than perfect lighting conditions.
Good scopes are not cheap and can easily cost multiples of a quality rifle. I really enjoy a Schmidt & Bender 3-12x50 on one of my .22s and a 6x42 Swarovski on the second from top.
