No, not for this IF you have elements that you WANT to have some motion blur, like water.
The problem with PS is that the motion artifacts are horrible, hideous, colored geometric messes. If the in-camera motion compensation edits them out, great. You lose higher definition there, like on moving water and leaves, and maybe that's okay if some other element is sharper. Like masking. But if we're talking blur to show action, nice soft blurred waves, fuzzier clouds, etc, fergeddaboutit. It looks more like a lime green double exposure with moire.
You can see some examples here:
