After seeing this post I watched the shows mentioned. (Well I haven't seen Banshee yet, but it's on my list)
These are fantastic shows.
Fleming is the one I'm least interested in, though still very entertaining. And Rectify being my favourite, it blew me away with only 6 episodes. Wow.

I've bingewatched The Following and I wouldn't say it's brilliant but I am really intrigued with this cult idea. Very entertaining.
But I got to disagree with you, American Horror Story: Coven was the best of all three seasons.
