I would recommend
1.Durarara. Its got 4 seasons with the first having 24 episodes so you can spend quite some time with it if you like. It might look plain and boring at first bt its pretty cool it you watch it till the end.
Happy Sugar Life does look a bit too moe but its pretty nice
There's always Killing Bites
Hitori no Shita_The Outcast is a little confusing to me but its a pretty good anime
5.And finally there's Domestic Girlfriend
