Qrow's allows him to be present at many places simultaneously, while Raven's allows he to jump from a point in space to another, alike to teleporting.

We also have to bear in mind that we don't know their parents semblances. Just like Ruby seems to have inherited a semblance very similar to Summer's and Yang might have inherited a semblance very similar to Taiyang's, Raven and Qrow might have inherited semblances similar to each of their parents. I suppose another way of looking at it could be if Qrow simply seeing through their eyes so his ability would making him all-seeing, while Raven's ability allows her to anywhere at any time and thus sort of making her all-present.
