Wow, this almost matched me exactly! If you switch Fluttershy with Twilight and Discord with Queen Chrysalis, and it's exactly how I feel. Twilight, with her raw magical ability and her slightly insane (and sometimes completely insane) personality, she just comes out on top of Fluttershy by a little bit (sorry Fluttershy!). Discord has to be my favorite because he's like a somewhat-evil Pinkie, he's voiced by DeLancie (I loved Q in TNG), and almost died laughing when Big Mac tunneled underground and acted like a dog. But there's one bottom line to all this: all the characters are great, some may be better than others in our opinions, but they're all part of the show we adore, so they all get the brony love.
