Well i'm of the concept you can never depend on having the gui
version.
so CLI is my choice, if you can do recovery by doing CLI then by all means
use GUI if available, just dont be dependent on GUI as your only method of
recovery.
Take for example:
Does the OEM gui give you option to be able to extract out(manually
using dbms_backup_restore.restorecontrolfileto) a backed up controlfile that the
only place it is, is in a backup piece)? My guess is no way(i've not
tested it though) as I'm trying to make sure i'm totally up to speed and can
recovery from any disaster at the command line before even looking at the
gui.
my 2 cents worth.
