personally, I think you're compareing apples to apples. Both scopes have issues that some people don't like. All in all, the difference between 4x and 5x is negligeble. Both scopes have problems with brightness at their high end in low light conditions. Their objective lenses are the same diameter and of similar quality, as are their exit lenses. As for rare earth coatings, which scope is newer?
That's the criteria I would use. Buy the newest of the two. If they are the same age, buy the one in the best condition. If they are new, buy the one that appeals to your eye. They are both darned good scopes for their nominal values.
You won't go wrong no matter which one you choose.
