Really my thoughts are as follows...
1. havn't seen it so i am not going to judge.
2. I am a big naruto fan so that is a must watch
3. Deadman wonderland. not that great. I just don't like its story line.
4. I don't even consider attack on titan to be an anime, it is more of a cheesy american knock-off.
5. I have never even heard of another :3.
My personal favorite list and must watch list is
1.Naruto shippuden and Naruto.
2.Bleach (not so much for the story line as it is awful, but for all the epic fight scenes).
3.One Piece. Has a great story line and also lots of fight scenes.
