If your looking for long running animes like naruto/bleach/fairy tail (200+) then Gintama is also good. Not as action heavy as some of the animes (thought the few serious fight scenes are REALLY good imo) but has a lot of jump aspects. If your looking for something dark like AoT I'd go with Tokyo Ghoul.
There are a couple of good horror animes like Another, Blood-C, and Higurashi. Another has lot of messed deaths in it like the Umbrella scene, while Blood-C has a lot of blood and gore in the fight scenes.
