Seekins would get my vote. I have a PH1 in 6.5prc and a PH2 in 28nosler and they are both hammers. The VX5HD is a descent scope but I prefer the Zeiss V4 in that price range. Never owned a VX6 but if I were spending that kind of money I would be looking at nightforce, you can pick up some great deals on used NF here if you watch the classifieds closely, the good deals don't last long.
