DearS

If you liked DearS then you'll most likely like Chobits, this doesn't necessarily work visa versa though. The main protagonist is a guy with little or no experience with women and somehow a cute girl (in Chobits a computer, in DearS an alien) has to live with the main protagonist. In both anime the girl needs to learn a lot about the human world which results in ecchi and funny situations. Chobits is deeper than DearS though, which is why I wouldn't necessarily recommend DearS to Chobits fans.

They're both comedies and slice of life shows and they're both very random and funny. Lucky Star is a lot more 'laid back' though, while Minami-ke isn't as 'laid back'. Also, Lucky Star has several references to the Japanese culture and to several anime.

Well, they have a similar feel to it and they're both slice of life and comedy anime. The difference though is that Lucky Star has references to several anime and to the Japanese culture. But other than that, both shows are pretty similar in following the lives of a group of high school girls.
