I like how it has so many modules to help with different tasks, i think its easy enough as an admin user but you can also make use of some more complex features if needed by using knowledge from other users who are better at them than yourself.
Some things have changed since we used candorworks previously which was very confusing when trying to find out what had been updated/changed over time! If your looking for something simple then this is perfect - maybe try one or two extra modules first before deciding whether they're worth paying full price? We were solving our email marketing problems in terms of being able to target specific personas within emails without having too much data entry required.
