Everyone above pretty much nailed it in my opinion. I have angled, the things I like about it are its very versatile in angles you can see from one position without moving because you can rotate it on the rings and look way left and way right. The other thing I like about it is I can digiscope with it and on flat ground it angles my camera up for easy viewing and up hill (which I do a lot of because my bear bait is up hill from my blind and I record all of my kills) it makes the camera sit level. so its very good for that. the cons are its harder to aim, although with practice its not much of an issue. using from a truck window its a little harder to use. not impossible because i use mine that way all the time. I can way there are going to be cons to both. I dont think you can go wrong either way because no matter what sometimes you will wish you had the other.
