Attack on Titan. May seem like basic Shonen horror but it's not. It literally changed genre every season from Adventure, to spy novel, to conspiracy intrigue. Give it a try (Season 3 and Season 4 part 1 are no bullshit some of the best things on television. Not anime, television period.)
Hunter x Hunter (though I admit the first few episodes are mid. Once you get to the Sky arena tournament arc, shit takes off hardcore)
The 86. Watch it. It's awesome.
