The feature sets are different, but both tools have a built-in configuration profile editor and can be used to install configuration profiles on connected iOS devices. The profile creation process is pretty similar, but there is a major difference in installing profiles on devices. iPCU allows you to modify only one device at a time, while Configurator allows you to configure lots of devices simultaneously.
sorry for not responding sooner. I don't suppose you'd fancy walking me through the process of adding a new profile using Configurator? Let's assume just one iPhone 4S with no profiles currently installed, with the aim being: to install a profile (previously prepared in Configurator) adding a new calendar syncing service; and to make no other changes whatsoever.
Also, would you be able to sum up the ramifications of using Supervised mode? There are some Restrictions in Profiles that seem to only apply when supervision is turned on, but it seems Supervision does more than simply make them available.
Thanking you in advance.
