Hacker News Reader

I can't speak to "best", but I can say that I've been very happy with BazQux Reader. It has good keyboard shortcuts, is very fast, lets you make filters within your subscriptions, has a good in-reader article view, a good mobile site (no app, which I like), and also allows to subscribe to see social media sites if that's your thing. I had previously used Feedly and much prefer BQR

I moved to Feedly after Google Reader shut down and have been using it ever since. No complaints.

There are quite few readers you can try:

InoReader (https://www.inoreader.com/)

FeedBro Chrome extension (https://chrome.google.com/webstore/detail/feedbro/mefgmmbdai...)

A little google will give you many.
