I believe distortion correction causes a slight loss in resolution in parts of the image depending on the type of distortion. Is it preferable to correct for pincushion or barrel distortion for VR, or is the difference negligible?

Correcting distortion shouldn't lead to a loss in resolution per se, but it can cause some distracting artifacts. The reason we don't lose resolution is because we are remapping the pixels of the source image to their undistorted points (using a pre-computed inverse distortion model) and interpolating the rest of the image.
