Going off of the above commenter, majority of the R. Students  are quite rememberable.

The Rainbow 9 - They were loved by the fandom, and the fandom was extremely disappointed when they made their departure.

The Study-Kuns - They, too, were noted by the fandom, while not one of the most popular students, they did have a lot of fans.

The (old) Delinquents - They weren't as popular, nor were they very rememberable, but they did stick for a while.

The Test Duo - Victim and Witness, both unpopular, yet simultaneously popular, they have a lot of fans, yet due to their absence in the modern game, not many people know them.
