I'm going to give a little edge to the NX8 in the glass department. I have 3 VX6HDs and they all track perfect and definitely lighter but for some reason the NX8 seems a little clearer to me. Big edge to the NX8 in toughness though..
I was running my NX8 the other day on my Vudoo V22. I was cranking the scope to its max 60 moa back down to zero all day. I was able to make hits a 400. Not bad for a 22 LR. I'm very happy with the scope.
