I have heard both of them and heard that Charlotte was good. My sister suggested me to watch Shugo Chara. But I dropped out of it. I might re watch it. I also mean that I wasn't hating. Sorry.
Oh, and I know an anime that at least I think isn't that popular. It's called Shugo Chara but I don't know if you'd like it. Oh and Charlotte is another anime you could watch! If you want to tho.
And I was never hating on anything. But, I see how you would get offended. Sorry! >~< I didn't mean to phrase it that way. This is exactly why I can't keep friends.
