Machikado Mazoku and Lucky Star are two slice-of-life series with cute female leads, bright art styles, and similar humor (even if Machikado Mazoku has a fantasy side and is more cartoonish with its humor than Lucky Star). Yuko and Konata make for very funny main leads in my opinion.
Machikado Mazoku and Ojamajo Doremi are two funny magical girl shows that have a main character be someone who isn't very good at what she is expected to do. Both are also directed by people who are no strangers to directing magical girl anime (Junichi Sato famous for shows like Sailor Moon and Princess Tutu, and Hiroaki Sakurai has worked on shows like Akazukin Chacha, Nurse Angel Ririka SOS, and even one of Ojamajo Doremi's later seasons).
Machikado Mazoku and Bottle Fairy are two fun series to watch if you are looking for a slice of life comedy with cartoony humor and some magic. The art style and characters in both shows are also really cute! (Both also seem to use same/similar sound effects...)
If you like anime filled with cute girls, these two anime are must watch. Both are extremely cute fantasy series with great character designs. In Endro the good girls try to beat the demon lord, while in Machikado the demon lord tries to beat the good girls.
Major difference is that Machikado is a fast paced comedy, while Endro is more relaxing.
