I have been asked by someone this but as I've only seen Death Note and Attack on Titan I don’t know what is along the same lines. Do any of you have any recommendations?

I've been watching anime lately, getting to know the genre, and still very new. Loved Neon Genesis Evangelion and Death Note, excited about Attack on Titan, but I'm still early in the first season. What would you recommend that's of similar tone/scope/etc?
