I played your track then went in and flew another crazy flight myself. I do feel I have the same control either way when doing extreme maneuvers. Though the FD is still my prefered choice when I go extreme, as there's just too much "grip" from the AP with it off. Otherwise I bob around all over the place and have to really hold the cyclic in place tight to fight it.
Also the trim has a lot less affect over the FD, than without FD. For instance, if you were to trim a tight bank in one direction and try to change direction and without trimming, you'd notice the force being applied by the AP (with FD off). A neutral trim in level flight to start with is much easier to control when banking. I still trim while using FD as there is still some input from the trim, but nowhere near as much.
Like you say, in the sim it's a matter of preference where IRL it would be common to use full AP (I suspect).
I just see it as another tool to use as needed.
