Mahou Shoujo Lyrical Nanoha A's, Mahou Shoujo Madoka★Magica Recommendations
The shows are both content and market-wise similar. Dramatic story, lesbian attitude, darker atmosphere than your average CCS, target older rather than younger demographics, oh yes and magical girls too.
I put my rec on A's because I seriously never watched the first Nanoha. My knowledge of magical girls genre is limited but these similarities are true and clear, see for Yourself.
The theme of magical girls in combat filled with action plays a central role in both of these epic series. Although Madoka leans into more of the psychological side as well, both of these anime(s) draws spectacular battle scenes that are pleasant to eyes of viewers interested in action.
