2d And 3d Motion Blur Difference

i have a scene where i have a still environment where nothing is moving but the a shaky camera imitating a handeled camera:

i want to apply motion blur but will the 3D motion blur be more accurate than the 2D even if nothing is moving?
or is it waste of time using 3D motion blur since nothing is moving and because 2D is way to faster?

Yes, it can account for occlusion of the objects, and reappearance too. 2d blur only has 1 visible data sample so it cant estimate how reflections and highlights behave.
