I have studied via both methods (External = B. Social Work through CSU & Online =B. Ed (Primary through Curtin Uni). To be very honest, although it took some getting used to, I much prefer online. I found that this mode allowed for much more interaction with other students and tutors. After a 4yr degree, finding space to keep all the printed material of an external course also became an issue and I ended up throwing lots of material out!. Although, I have to say, that towards the end of my external course, the university (I guess as a means of being environmentally friendly) decided not to send out all the printed materials anymore, and would instead sent a CD rom that contained all of the required readings etc.
