Well I guess that depends, what do you enjoy most? I'm into Shonen types of anime (action packed, "boy" oriented anime) so that will be most of my recommedations. The other alternative, I believe, would be called shojo (lighter-hearted, romantic, "girl" oriented anime). Want mystery; go with Death Note. Fun loving action? Fairy Tail/pretty much any of the mainstream ones (One Piece, Naruto, Blue Exorcist). Darker more gruesome action- Tokyo Ghoul. Fun but with "Fan Service" (Showing off cleavage and whatnot)- Kill La Kill. Darker with fan service- Dance in the Vampire Bund. Light, old school, mechs: Gurrenn Lagann. Darker, newer, more in depth survival action: Attack on Titan. Short and sweet, lovable characters, some fan service/ecchi, AND action? Seven Deadly Sins. Want something more philosophical and magical? go with Fullmetal Alchemist. (A lot like a more serious Fairy Tail). And finally, Something purely visually stunning, and a fun mix of new aged magic and old warriors, Fate/Zero or Fate/Stay Night. Again, everything depends on how light-hearted, action packed, loving, or anything else that something is that you might want to see.
