Everyone sees differently, but Ive got three of them, and three of the 2.5 to 8 and I spent hours early morning and late at night comparing the two models, and any difference is in my opinion very slight. I prefer the 2x7 because its slightly smaller and lighter and to my eyes at least is 99% as good as the VX3. Its also, in Canada, about $200 cheaper, which may have affected my vision.
