I use RSS everyday. Practically everything I read arrives on my screen via RSS. So it matters that my RSS readers work for me by getting out of the way.
I’m always trying new ones out, most recently Micro Blog’s Inkwell. It’s good. It works. I like it. But it’s missing something and I don’t know what.
In contrast I have never stopped using Sublime Feed for medium to long form reading. It works just the way I want. I couldn’t really tell you how or why, it just works for me.
For brief scanning of short form posts, news and social accounts, I use Reeder, to which it is very well suited. The opposite of Sublime Feed.
Horses for courses.
Other good readers I have used, like Inkwell and Unread, fall between the two short form and long form stools.
