It depends on the context and quality of the learning environments. It can be a bit like comparing apples and oranges.
If your context is P-12 school then physical face to face contact is important and the Web-based learning can augment and extend the learning well beyond the classroom.
Post school, Web-based learning can be more mainstream as adult learners are often more independent. You still need to have a social presence, but that an be achieved in a virtual environment with well trained facilitators.
Appreciate the challenge in your postings.
