Whoa, lot of hate towards Fairy Tail. O_O Anyways I haven't watched Blue Exorcist, so I won't include it; but here's my opinion:
Fairy Tail: (Based off of your Zoro picture, I'll assume you like One Piece. Fairy Tail is pretty much like a shorter version of One Piece and both follow the same idea of "friendship/family is what makes you powerful" The show stopped for awhile, so if you're going to get into it, now's the best time.)
Code Geass: (Can't talk much about it, since I've only seen 11 episodes so far, but it's pretty good in my opinion.)
Dragon Ball-dbz kai-dbz gt: (I would definitely save this one for last, simply because of how long Dragon Ball, Dragon Ball Z, and GT are. However, even though Kai is a shortened version of the story, I would watch the original; it's just overall a better experience in my opinion.)
