Been using free tier Feedly for many years now. It’s “good enough”. Before that I used Akgregator, which did a pretty decent job for a local app.
Other odd RSS adventures: I played with self-hosted Tiny Tiny RSS for a while, and it is actually pretty awesome. It’s automatic filtering and tagging capabilities were amazing. But I got tired of maintaining it. I toyed with NetVibes ages ago – it is a “dashboard” oriented web site, with RSS support. It worked pretty well actually, but the UI is … unusual. It used to be free. Maybe still is. I don’t know. I found myself using the cleaner and simpler “good enough” Feedly more.
It should be pretty easy to move your RSS feed collection between apps/services as most of them support OPML format import/export. So just go ahead and try stuff and see what you like. (Just check first that it supports OPML import/export.)
