By far the easiest to use GUI for remote admin, but it is still a little heavier on resources of course. Usually not a problem unless you are REALLY stretched thin.
it's great if you want to give other people an easy way to control aspects of the backend of the server, but dont trust them in your shell / they do not know command line.
Also the only web cp ive seen with a gui for setting up permissions that are linked to specified perms plugins.
works great with FTB server too, you just have to rename the server jar to one that mcmyadmin can recognize.
