Nanatsu no Taizai is a really good anime. One that I sorta prefer over Fairytail. A lot of Shonen are pretty much the same but if you can deal with the pacing One Piece is really good if you give it like 60 episodes before giving a definitive answer on if it's worth continuing.
Fullmetal Alchemist Brotherhood is a great anime very dark though. D-Gray Man Bleach I guess. Hunter x Hunter is an anime that is good but it got put on a hiatus due to the manga creators back issues or something and only recently started making more chapters. Soul Eater Magi Katekyo Hitman Reborn! is also really good.
