Caveat up front: I can't say that I've had a lot to compare my VXRs to except a Leupold VX 6 1-6, Vortex PSTs (1-4 & 2.5-10), and Vortex Diamondbacks 3-9.
That being said, I love the VXR illumination with the motion sense technology, both in the VXR and the VX6
My current go to night hunting scope is a VXR 2-7 and it works very well on my DIY night vision rig. Pics and video here:

I also have a 4-12x50 with Ballistic Firedot and had a 1.25-4 with the Firedot Circle. If I did a lot of daytime hunting, the 4-12 would be my main scope, but the 4x FOV is too tight for my style of night hunting.
The Firedots are bright enough to use during the day with both eyes open similar to a red dot. I ran the VX6 as an Aimpoint replacement but the 1.25-4 had a little too much distortion on the low end compared to a true red dot.
The VX6 didn't have as good of night resolution through my DIY NV as the VXR 2-7 does.
I'm not a fan of the illumination knobs on the Vortex PST series and the illuminated reticle in the 2.5-10 washed out my NV even on the low setting. The reticle on the PST 1-4 was not bright enough to use during bright conditions during the day.
Overall, I'm a fan of the VX R series and think they are a good scope for the money when you want illumination.
Full disclosure, I have a new VX3i 1.5-5 scope arriving tomorrow that will swap back and forth with my Aimpoint T1 on my 14.5" AR that is set up as a HD/close range coyote rifle. I decided that I didn't need illumination on that scope since it gets used with lights and not NV. I'll see how I like it; it may get swapped out for a VX R 1.25-4 in the future!
