Akame Ga Kill
Hunter X Hunter (Must watch)
One Punch Man
Hellsing Ultimate (Pretty bloody and adult oriented. Watch if you want)
Bleach (Skip fillers. Your mind will literally die from how stupid the fillers are)
My rule of thumb is if a person wanting recommendations doesn't list a favorite genre, just list the best anime, period. That's because when I myself seek out anime, I never say to myself, "gee, what mediocre anime should I watch next?"
I can whip up an impressive list if I put the thought into it, but the OP has all but abandoned this thread.
