Typically guys are using firm rabbit ear style bad as more of a “rest”. The bag is doing 95% of the work of keeping the rifle in place while the trigger is pulled. Once you learn to fully engage the rifle with a tactical style bag, you can shoot as good as if your rifle was in a rest but you can do it from a small tactical bag while controlling even the heaviest recoil.
The question is not which of the 2 bags is better. That’s like asking if a hammer is better than a screwdriver. They are two tools with different functions. The question is what is your goal. A benchrest type bag is typically used to hold the rifle in place while you pull the trigger. A tactical style bag is used to add the final amount of stability needed once your body is aimed at the target and the rifle is connected to your body.
If your goal is good groups in a benchrest/f class type setting then a BR bag is fine. You don’t need to spot your own hits and can strictly control your timing and set up to make it fit your equipment and the terrain.
If your goal is being able to drive the rifle effectively from multiple positions and/or situations on the fly, a tactical style bag is what you should be looking at. So both bags do what they are supposed to do. It’s a matter of asking yourself what your goal is when you close the bolt.
