Powdr speaks truth. "Best" in this instance gets into scopes costing far more than either that the OP mentioned.
All I can say is that the VX3 from 4-5 years ago was spanked pretty good by the same-era Conquests, to my eye. It was a color balance thing as much as anything; the Leup coatings went a bit yellow in really low light and the Conquest was more blue-white. Made a very noticeable difference for me, at the bitter end of low light, in the western Oregon jungle.
A LOT has changed since then, optically, and almost all for the better.
