Oh misintrepretation, I would agree DJ and Stephanie were much more preferable as roomates because I loved how DJ would struggle for independance and Stephanie continued attempts to spy on her.
That's definitely one of the things I liked about DJ and Stephanie as roommates. Also, Stephanie and DJ had more siste to sister bonding as roommates (which continued to an extent in the later seasons when they were no longer roommates). There was also the feuding between Stephanie and Kimmy, and the insults that went with it (which I love), which kind of died down after DJ got her own room.
Stephanie and Michelle as roommates mostly just got into fights about the use of their shared space. Michelle never really had Stephanie's sneakiness. Stephanie and Michelle as roommates had the odd heart to heart, but these didn't have the same depth as did the heart to heart talks that DJ and Stephanie had.
