I believe Majikoi is more interesting than most other VNs out there for the themes it deals with. That is, sex. I know it's an eroge and not a serious VN with a deep message. But heck, I love the humor in Majikoi. It knows how to mix sex with humor in just the right way, while still keeping a somewhat serious story and characters you care for.
You don't get a shit ton of drama with deep romance (often unrealistic, cause that's not what teenagers do), and you don't get a shit ton of sex with no true character development (like many, many, MANY +18 VNs). It's just the right amount of each.
I tried Little Busters a while ago, which has a similar setting and perhaps even a direct parallel in most characters. And while by no means it's bad, it lacks charm.
