I've got 4 of the CDS Leupy's, 2 of them VX3's, and my buddy has a couple, and another buddy has another couple. Over the past 3 years we've had zero issues with tracking, repeatability, or anything else. Can't speak for my friends, but my two VX3 CDS scopes have had about 500 rounds through them combined. If I were a tactical dude (which I'm not), and my desire was to spin the ever loving' pizza out of my turrets every day, then I'd probably go NF. As a regular hunting type, I'm not sure you will find a better hunting scope than the VX3, unless it's a VX6!
I know this isn't exactly what you're referring to, but I've had two 50+MM NF's side by side with my VX6 for 3-4 days at a time, and the VX6 was superior optically in both cases. I could dial out to 900 and everywhere in between zero (200) many times, doing everything the NF did.
