I am assuming you are referencing the Zeiss V6. I have actually made a change to them. I can't speak to an exact comparison to the vx6hd as I haven't had them side by side. I had the V6 next to a Swaro X5 and it compared very favorably. I don't find an illuminated ret a big selling point for me. When I have had the V6 out in low light, I didn't feel that I was lacking. I went with the MOA reticle given to better match up with other components in my set up.
