It can be confusing.
But, look at it this way: any of the quality manufacturers put out good products. So, stick with one of the quality manufacturers, you get a good scope.
So, now you're going to ask "who are the quality manufacturers?"
My answer is (in no particular order): Nikon, Zeiss Conquest, Leupold, Burris, Pentax, and the upper lines of Weaver, Sightron and Bushnell.
I'm sure there are other brands I don't have enough experience with to rate, and other folks will have other preferences.
