Both animes are about table games with characters who are aiming for the very top.
Haruhi Suzumiya and Yukita Morita are extremely alike. You'll like both shows just based on their personalities.
Harem shows with Magic... What else is there to say?
It's the whole idea that the female is "God" and the male has to put up with them! They are both very slice-of-life with a bit of comedy thrown in.
K-ON! and Lucky Star are both easy-going, slice-of-life anime that have practically matching character personalities. K-ON has a hint of a story-line, but ends up with the pointless and random almost every episode, just like Lucky Star. If you loved one, there is no way you'll not love the other.
