NewsBlur is open-source with cloud options. Feedly wastes too much screen real estate, NewsBlur has an AI option to prioritise articles based on your taste.
It looks cleaner, but it's not as practical as NewsBlur, which is built for speedy consumption. I love that NewsBlur shows me article edits - sometimes they bring a great aspect you don't get by other RSS readers. Its social features beat what Google Reader had in store as well.
I took a peek at Newsblur. This Reddit-ish UI puts me off too (plus no dark theme...), but I can't rule out it beats Feedly in terms of functionality.
I wonder if their mobile app is any good - while Feedly the webapp is ok, Feedly on Android is severely lacking. Always loading news updates when it's opened (doesn't allow you to skip this step), and if you switch away from it, there's no guarantee it'll return you to the same place... lame
