While frequent use of the function really caters to photogrpahers exploering many poses and such, for the display purpose, it's more the option to find a pose for everything on your figure how you want it. While most might choose a pose and never move the eyes again, they still might need the PERS to make the eyes right for that pose. It does enhance 3/4 view poses, and if future figures are as easy to manipulate the eyes on as Batman, I don't fear breakage problems, Joker sticks a little, not sure how MJ's PERS are. I especially like the Batman style for getting at the control, leaves the head to be seamless, as nicely blended as Joker is, it's still not as nice as no seam at all.
