K here is my opinion having looked thru all but not used any of these scopes. THe redfields are a level above the banner and bsa. THE glass is much better. THE bsa is an affordable lower end scope. Banner is the same, bushnell is a first rate company but the elite series scopes are on a level above the banner/trophy series. I would question their warranty as well, but banners dont cost as much so whatever. I actually heard the elite series come from an entirely different factory in a different continent than the bannners. Redfield is a quality scope, i say this because i was impressed with their glass and the number company in America with the number one warranty makes em. Leupold stands by their products gentlemen, they can do this becasue they do not make or endorse any product that sux. my opinion is based off experience.
