Both stories include RPG elements (though 1/2 prince takes place mostly in an RPG while in WCC the protagonist has RPG relevant powers). Both protagonists are a little ditzy, but still heroic.
Both stories are slow paced, with likable characters who have warm and fuzzy interactions that will make you smile.
Horimiya and Namida Usagi both start out with a girl and her classmates judging a boy because of his appearance and social awkwardness. As the female protagonist gets to know the male protagonist her opinion of him begins to change and they become close friends. Then there are hints of romance... The art and the story in Namida Usagi are not as polished as that of Hormiya, but the characters are interesting, and there is enough to make you want to read the next chapter. The drawings and character development in Hormiya is very attractive, though the story is shorter (so far). Still, the ideas behind the stories are very similar, so if you found one interesting, you might like to check out the other.
When reading Basara it really reminded me of Nausicaa at many moments. Both mangas have an epic feel and really tough heroines. Both are daughters of their villages' chiefs and have an important 'destiny' that involves healing the world after a lot of destruction. Both characters have a cute pet that follows them around. They also are both very charismatic, easily becoming friends with almost everyone. Basara hints at environmental concerns, while Nausicaa makes it one of the main topics of the story. Sarasa is more inclined to fighting that Nausicaa is. Both stories have very emotional moments and a large cast of complex characters. Basara however has a more clear cut, and happier ending (in my opinion). Basara is also a romance (where as Nausicaa is not) and it has a lot more silly moments than Nausicaa. Still, if you enjoyed one I think you might enjoy the other.
