Drifters is a great anime (same people who made Hellsing) also Ajin is really good. A few others I would recommend are Assassination Classroom, Overlord, Hai to Gensou no Grimgar, Katsugeki Touken Ranbu, Code Breaker, Samurai champloo, Afro samurai, K, Initial D, Gangsta, Gate, Divine Gate, and Devil may cry Just to name a few of my Favs.
Also if you want a good sports anime check out kuroko no basket (basketball) Hajime No Ippo (boxing) and All Out (rugby)
