cPanel, Direct Admin, Dreamhost's Panel.cgi, and more. Lots to choose from, but which one is best? Apple even has its own server admin, too. And GPLhost has one, how to choose?
So far, I have my complaints about them all, and none have shown themselves to be the best. I'm sure in good time, one will emerge as better than others in some areas, and others will be better in different areas. Do you have a preference? I'd love to hear about it.
