I have so many rifles I just can't afford to spend 800.00 on each one so I had to compromise, but to tell you the truth I like them better than my vxIII 6.5x20x50 3 for the price of one, makes it an easy choice when your on a budget, I think if more people did what you and I did they would buy one too.
I am loath to tell anyone what brand of underwear, toothbrush, or scope to buy. My criteria included side focus, sunshade included, target turrets, fine reticle (no 'gismos'), and a sharp image. Please note that brightness was not on my list, as I don't care to hunt at night and most any scope will be more than bright enough in broad daylight. In more than 40 years of shooting, I have not scratched a scope tube, much less beat one up. For my purposes a scope needs to be sealed, repeatable, and able to withstand the recoil of the intended rifle. I do not require extreme impact resistance.
On my list of 'wants', a fine reticle and sharp image came first. The Nikon Buckmaster provided those. I have had other scopes and several with one trick reticle or another. In the end, I prefer simplicity and ease of use.
Playing with telescopes taught me a lesson or two about sharpness in optics. I look for sharpness in the very center of the field and discount everything else. A telescope (including a rifle scope) is intended to have the object of study centered in the field of view. It is possible to grind a lens for optimum sharpness in the center of the field, but the edges of the field will suffer. For a scope or binoculars to have a 'flat' field (uniformally sharp edge to edge), then the center must be softened and the edge sharpened. This gives the 'sharpness' a degree of uniformity at the expense of absolute sharpness in the center. Apchromats compensate for this optical phenomenon to a large degree, but I have never seen apchromatic lenses in any rifle scope and I couldn't afford one anyway (would probably be several thousand dollars).
Most scope manufacturers seem to flatten their field of view. This gives the illusion of a brighter image, as well as providing an advertising gimmick (sharp, edge to edge).
When I looked through the Buckmark, there seemed to be a barely noticable degredation of the image near the edge of the field of view. This is precisely what I was looking for and had a bearing on my decision to buy it. That degredation signaled that the lens designer optomized the curvature of the lens system to provide the best image in the center of the field of view.
Obviously, not everyone shares my preferences in image presentation. I made myself happy.
There can be a noticable difference in brightness among a particular group of rifle scopes. Some of that difference may be attributed to the lens configuration I mentioned above. It would take a carefully controlled laboratory test to determine the actual light transmission characteristics of that group of scopes and the results would only apply to those particular scopes, as light transmission can vary quite a bit from one piece of glass to another, even off the same assembly line.
I know just enough about optics to be dangerous. I am by no means an expert. For me, optics is akin to art. I wouldn't know good art from bad art, but I know what I like.
I highly recommend testing scopes side by side and buying the one that looks 'right' to you. If possible, buy that very scope, not one "just like it" in a box off the shelf. If one looks very good but isn't quite 'right', ask to see another off the shelf and see if the second one looks 'right'. You might be surprised at how much variation there is in a batch of the same model, regardless of cost. The higher priced scopes may be more uniform, unit to unit, but it is simply impossible to build several of anything that are exactly alike in a production environment.
Not everyone shares my want list. That is why there are several brands with innumerable features in a price range from less than $100 to several thousand.
I was an amateur astronomer for many years. I demand certain things of optics, but I do not demand everything of optics.
When I found a scope that met my expectations, I bought it. Simple as that.
