Glass NX8 vs VX6-HD

I'm tore between these two scopes for my next build. Looks like I might be buying both and selling the one I like less :eek: or I might keep both and start another build:p
 
I read a couple reviews on the NX8 and they said the center dot / red dot on the illumination is pretty large and makes it hard for long range precision shooting. Basically they say it covers approx 5" at 300'ish yards.
Any input on this? I was thinking about getting one for my next build but this info has me concerned. Been looking at the Kahles 3-18 instead but waiting for the rifle first which is 9 months out still
