Wordpress popular posts plugins
 

Which Wordpress popular posts plugins do you guys like best?

I'd like something I can display on a sidebar, but which does not display numerical stats either publicly or anywhere non-admin accounts can view it. Ideally, non-admin accounts should have zero visibility and I'd like to have admins be able to see what is popular without necessarily publicly displaying it. I'd like to be able to display by category as well.

There are 5 or 10 commonly used plugins for this, but I'm finding it challenging to compare them.
