I would highly recommend both of these shows to those who love music-based anime with a majority cast of pretty male characters. The music is varied in the genres, and the characters are all charming in interesting ways rather than generic stereotypes, with their own personal stories or struggles.
Both shows are about friendship and dreams, not giving up, living up to expectations and music. The cast is very similar (a lot of shared seiyuus), protagonists are loveable. Both series feature conflicts about aiming for your goal when things go wrong versus choosing the easier path and giving up. Also twins.
