I have both and prefer AB.
Primarily because you can input and exact range rather than just get a drop table. I usually deal with known disatances and/or LRF targets. So, I know the exact range. AB (and Strelok Pro, etc) allow you to put in the exact range and get the result. They also produce a table if you like that. However, I like the exact range feature. Ballistic AE does the "HUD" but you can only input the nearest 25 yards (or whatever the setting is)
AB also adds custom drag models if you want to try to use their doppler gathered data for potentially better output.
My go-to is usually AB or Strelok Pro. I'm still bouncing between the two. They are usually very close and I'm the problem behind the trigger, so it's hard for me to figure out which is more accurate because I'm usually the one that's causing the problem.
I've had great success with Strelok Pro and I don't know if the added price of AB is really worth it unless you really want to use their custom curves.
If you know the distance you can put exact distance in Ballistic AE. You put the target distance as maximum distance and the target distance as range increment and it gives you the exact dope for the distance.
