I got a ta50-4 recently, and it has a lot more eye relief than 1.4 inches. My scope is mounted about in the middle of my receiver where I have to have a nose to charging handle position to get a complete sight picture. I do not need the full sight picture unless I'm using the magnification only, and it is easier for me to use BAC without a full sight picture. As far as losing the sight picture, it doesn't happen if you are familiar with your rifle and how you hold it. As far as washout goes, you have a big black cross instead of nothing at all like a red dot.
I have never used a 2x so I have no comparison, only praise for the ta50
edited to add:
It will not replace your aimpoint. It is not all that precise using BAC, but sometimes (depending on what its used for) the 3x beats out the need for reflex precision and BAC is good enough to get it done.
