I use the old Reeder still (don’t care for the new one at all, it’s pretty crappy and the subscription has zero value for me), and NetNewsWire is still not as slick on iOS, but the piece is largely on point.
Also on the old Reeder (v5), with a local FreshRSS as the back-end. It's fantastic on Mac, iOS and iPadOS, and I have no desire to move to the new Reeder or any alternative.
