This screenshot comparison shows very clearly that super resolution has some clear advantages over sharpening. In this case I used the sharpen filter in Virtualdub for the comparison. From this example is it very clear that compared to sharpening, super resolution has more detail, while having less noise enhancement, less ringing, and less aliasing.

So, unlike some critics stated in the past, super resolution does indeed enhance detail, while simultaneously reducing noise, ringing, and aliasing compared to standard enhancement techniques.
