There actually isn't much of a similarity between both these manga, except for the fact that they're both Shounen Ai. And that the mangaka use unnecessary chibi/cartoon figures to draw their characters in order to make the appear funny or moe, and frankly, that killed the enjoyment for me. But if you're into such art, you should def pick up the other manga.
