Just logging my experience, I tried the ATN X-Sight II HD 4-14, which they don't list on their Web site anymore but seems identical to the 3-14x there now. It was a very interesting and innovative product but VERY heavy. I didn't like the mounting options, either - I had trouble getting it in the right position for proper eye relief. It was always a half inch forward of where I wanted it. Finally, the ATN product is pure "electro" - if its batteries die, your hunt is over. In the end, I returned it.
I didn't think the ATN was a bad product, per se, it just didn't fit my needs. I think hog hunters might love it - on a shorter AR platform where you might want some low light or thermal imaging and an extra pound might not be a big deal, it might be fine.
The Burris is a much simpler product and you'd probably be happier with it if that's what you want, although it's a hell of a premium for a range-finding scope over just carrying a separate rangefinder unit...
