Which do you like more? Active or Rabbithole Classes

Having rabbit hole classes means I can send a sim off to class while still being able to play with my other sims. As someone who plays with large families I find this preferable. I just hope we can attend classes while still living at home.
As it is, I found active classes uninteresting in the Sims 3 and classes being rabbit holes means that more time was probably put into the other more interesting parts of attending university.
