sambubba, that would be my question too. In side by side comparisons of both scopes, I have found the opposite. In my testing the SII is optically better. The resolution and color spectrum is better than the VXII. The SII's eye relief is very comparable to the VXII also.
In the 200.00-300.00 range, the only glass I have found better is the 4200. The SII and VXII both have better eye relief than the 4200 but if shorter eye relief isn't an issue, the 4200's are the way to go in that price range.
Hope this helps and have fun,
Rob
