if you want stuff like death note, watch:
- danganronpa
- zankyou no terror
- psycho-pass
- higurashi/umineko no naku koro ni
personally loved these (ESPECIALLY THE LAST ONES) and i find them somewhat similar to death note.
as for fantasy/shounens, id point you towards some very well known series such as:
- shingeki no kyojin
- no game no life
- hunter x hunter (2011)
- toaru series (railgun and index)
- sword art online
i only put sao in there because you've seen three shows that are extremely similar to it. otherwise, i really don't recommend it, at least the first season is very bad. but feel free to give it a try, you might come to love it. railgun and index are pretty unpopular, but they were one of the first shows i ever watched and i really liked them. hxh might seem a little long, but if you give it enough time, you'll enjoy it a lot.
also, these aren't very similar to most of the things you've watched, but i'd still recommend them just because of how good they are:
- shinsekai yori
- neon genesis evangelion
- gangsta. (currently airing)
- shokugeki no souma (currently airing)
hope this helped. (:
