Hierarchy of internship sites?

I am trying to get a better understand of the hierarchy of internship sites out there for clinically-oriented students. Not sure if one exists. I have heard VAs take the top spot and university-based counseling centers are at the bottom (for reasons I don't fully understand). I'm not saying I intend to use this hierarchy to solely determine which sites to apply to - but it would be helpful to have an understanding of how the field views internship sites for post-doc etc.
