We have found that Google Analytics provides some more insightful reports when it comes to certain aspects of user activity.
I'm looking at using custom variables to help distinguish between course areas within the GA reports, like "HE" or "GCSE" etc. Also to indicate if a user is logged in or not.
We have some custom reports set up to show things like the average session time per day, distribution of course page views over the day. You can also get an interesting behaviour flow report.
