Opinions about scopes abound much the same as the ones about rifles, calibers, and bullets. If you like it and have confidence in it, what more can you say. Buy it. But, the real problem is trying to assess what it will do in the field for you alone.
I had a Vari-X III 2.5-8x for a few years. It was flawless functionally. But, at first light and dusk (critical first and last minutes of shooting time), when looking into shadows, I could not pickup the reticle. If you hunt at those times, you may find the same true for you with these models. If the heavy duplex is available, it would likely be a good option to consider and will help at those times of the shooting day.
