The next day, the teen's dream becomes reality when the girl – Homura – arrives at Mitakihara Middle School as a transfer student, mysteriously warning Madoka to stay just the way she is. But when she and her best friend Miki are pulled into a twisted illusion world and meet a magical creature named Kyubey, the pair discovers that magical girls are real, and what's more, they can choose to become one. All they must do is sign a contract with Kyubey and agree to fight witches that spread despair to the human world, and in return they will be granted a single wish. However, as Homura's omen suggests, there's far more to becoming a magical girl than Madoka and Miki realize...

While these series may seem miles apart, they both focus on a main character that can't completely decide which world they want to live in and what they want to do with it. Eventually, they finally decide and cause a very similar ending in each. Without spoiling, all I can say is if you liked the ending in one, or the struggle to decide what's right and wrong, and who to believe, it's definitely worth giving the other one a try.
Both are magical girl shows with actually dangerous villains, bringing in a horror element to the mix. However, both still contain the message of the importance of friendship that is a staple of the genre. Puella Magi Madoka Magica is darker with more sci-fi elements, but if you like one you should stand to check out the other.
Both involve ordinary person taken into world of magic and power to grant one wish. These series might not look so similiar on the first glance but after digging deeper into the storyline similarity is stunning.
