I have the SS16x42, and am VERY happy with it so far.
Since I have owned it for less than a week so my experience is limited.
Optics are very good. Images are bright and clear to the edges.
Reticle is thin enough to be highly visible in low light, but obscures less than .25 MOA of your target. Mildots are clear and precise. The ranging is very accurate and easy.
Adjustable Objective rotates with effort, but not overly so. It can be calibrated if the focus is off.
Target knobs are precise and easy to use. They are slightly mushy, but the click is still tactile and audible. They are actually infinitely adjustable. There is 120 MOA of adjustment, which precludes the need for canted bases at long range.
The body feels very rugged and is fairly heavy.
Eye relief is long.
Cost is $300
You will probably not find any better deals out there for mid quality optics.
It is not a Leupold, of course, nor can I afford one.
Reasons I chose it:
1) Price
2) 120 MOA adjustments
3) Magnification
4) Target turrets
5) Mil Dot Reticle
There were simply too few scopes out there that filled all these requirements.
If I can afford it later, I may have to drop some more cash and get a "real" scope, but for now, I have to shoot within my means.
BTW - The SS scopes were made under a military contract with the Navy.
