Tough to even have the discussion because it ultimately becomes a "Which is better: Ford, Chevy, Dodge?"
Your eyes, budget, type of shooting, and experience with various grades of optics will lead you to your final decision. If all you've ever used is sub $200 scores, then a vx3 is a huge upgrade. If you're consistently shooting 300+ yards, you probably never considered a sub $200 scope.
I love leupold and don't much care for vortex unless it's the Razor line of products. In general, you get what you pay for - very evident with optics.
