Josebd,
I have had an ATN X-Sight 4k for a year now and it has served me very well at my coyote bait site. It has a lot of features that I don't use, and like Burnsome I turn most of them off. I like the scope overall and really don't have any complaints except one, and that is the video. What I see through the scope looks pretty darn good, but the video appears to have part of the scene move about within the main scene, if that makes any sense. Video quality is not as good as what the eye sees, but it's not bad. It's a simple one-button push to start and stop video. It also has sound, which I like.
The battery is unbelievable and seems to last forever the way I hunt. Believe it or not, but I have only charged it twice since I have had it. Since I use it at a bait site, I keep the scope turned off until I need it, which naturally makes it lasts a long time. If using it out calling, then no doubt it won't last as long, but it's advertised for 18 hours.
Since the scope accepts 30mm scope rings, it can be mounted lower to the bore than many night vision scopes, which aids in better trajectory. I am sighted spot on at 60 yards since that's the distance to my bait site, but recently I took a skunk at 142 yards with dead on hold. I didn't refocus from the 60 yard setting but still the view was good enough for shooting. The scope does have a ballistic calculator which is a very good feature to have, especially if you are hunting over bait such as for hogs or coyotes at various distances. I had the X-Sight 2 and used the calculator on hogs in Georgia, making head shots at all distances I hunted. I haven't tried the BC on the 4k yet, but I assume it will yield the same results.
The scope has a continuous zoom from 3-14x power, but as you may be aware, the further you zoom the more pixilated the view becomes. I can zoom to 5x without much loss, and going to maybe 7x is not bad, but beyond that it isn't as good. You can still see and could shoot on the higher magnifications, but the view just isn't as good.
One negative is that the scope has locked up on me perhaps 3 or 4 times in the last year, causing buttons to be unresponsive. I simply hold down the power button for maybe 10-15 seconds which powers the scope down. Turning the scope on is simple with a short press of the power button. It boots up quickly.
As Kirsch suggested, you may want to go for the lower power scope (3-14x) unless you will do most of your shooting at longer ranges. The narrow field of view of the 5-20x may be difficult.
With the exception of the video view and the lock up, I haven't found any other issues with the scope. It's more pricy compared to other digitals, but also it is packed full of features if a guy wants them, though I personally don’t with the exception of the ballistic calculator. I like the style, design and ease of use of the scope. Resolution is pretty good too.
I haven't used the Wraith, but it appears to be a very good scope as Kirsch's videos demonstrate. If we could only talk him into doing some night time video, but he has such a love affair with thermal that he can't seem to break away. LOL. The only thing that I personally don't like about the Wraith is that it doesn't record sound. I keep hoping future models will correct that. But if sound is of no concern to you, then the Wraith might be a good try. It's cheaper and appears to be a good scope. It has very good resolution from what I have seen in night time videos.
Below are some 4k videos of three coyotes I took recently to give you an idea of what it's like. I used a T-20 illuminator for these, but last night I used a TR-38 illuminator that I got from the UK. It has a 2,000 miliwatt pill that works great at longer ranges, though it is too bright at 60 yards on high beam. The ridge top in the videos at 160 yards is well lit up with that illuminator. I don't have video yet with the TR-38, but that hopefully will come later.

Hope this has been of some help and will give you an idea of the 4k. Regardless of your decision on a scope, you will enjoy night vision like the rest of us. It's addicting. Good hunting, and be sure to keep us posted how it goes.
