Jealousy, fighting bad things, basically the same plot set-up.
Same dark mood and bishounen cast. Both of the main characters in ML and 07-Ghost share a tragic past. 07-Ghost is more of the fantasy and genre, while ML centesr around the daily lives.
Both contain a lot of references to other anime/manga works and are hilarious, especially SZS.
Same studio, references to Shana, same style, etcetera.
Both are about ayakashi and yokai, share a bit of story and they both have a Zashiki-Warashi in it. xxxHolic is pretty dark, while Natsume Yuujinchou is lighter and uses more colours.
Both have an almost female-only cast and main characters.
Both have a animal-like sidekick and are mostly about capturing things like animals and ghosts.
Both start off very shoujo, but Nanoha is a tougher anime than CCS and has more spectacular fights.
Both anime are about a magician group to solve a mysterious case and banishing evil. Touko and Iba also have both something special about a eye...
Both are school comedies and don't have a real story line. Lucky Star is the otaku version.
Both about a boy living in a inn, surrounded by girls. Mahoraba is the really cute version, Love Hina is the punch version.
If you like Sakura, Syaoran and other characters from Clamp, watch Tsubasa Chronicle! It takes place in an alternate setting, complete different storyline, but the characters are still the same! Tsubasa Chronicle also introduces two new characters only for Tsubasa Chronicle, Fay/Fai and Kurogane. If you like Clamp, you'll like this one for real!
