Been using and paying for newsblur for some years now. Absolutely love it
And many more:
Its cross platform and has an excellent Android app that I use. Has some nifty AI. text filtering capabilities that help to sort articles. It does both river of news and email inbox style rss display. Fast support as well and fairly active development that you can track on their repo
After Google Reader shut down I tried a lot of different services and Newsblur felt to me the most closest and natural successor. Its interface is simple and has been largely unchanged, so helps with muscle memory.
