If you mean "Administrators", that is the local Windows group, WebAdmins is an EPiServer group.
So, local administrators won't need an EPiServer account in order to log in, and to access /admin for an example. Good thing if you lose your password.

There is no Administrator in EPiServer, as far as I know. That would be the local Administrator account on the server, which is automatically created in EPiServer if you log in with it.

If you read the administrators manual.
On page 9, you see 4 different groups
Administrators, web admins, web editors and everyone.
And in the information about Administrators is says that this is the Website "super" administrators.
and in the information about Web Admins is says that this is the Website administrators.
What is the difference between Website "super" administrators and Website administrators?
Ok, you wrote "Administrator", I got confused :-)
Administrators is the Windows group. Everyone that is a member of that one will get access to /admin and /edit by default (because of the directory settings in web.config). And with these rights, you can go to /admin, and basically do everything (including creating new users.)
Web Admins is an EPiServer group, from which all members also have access to edit and admin. BUT - in contrast to members of the Windows Administrator group - you need an EPiServer user account to log in.
Apart from that, the users can do very much the same, regarding EPiServer.
Think of the Administrators group as a rescue when you forget the password for your epiadmin account (or whatever you call your episerver administrative account.)
