Been using Fluent for a while now.

I like that it lets you specify to open pages as RSS or full webpage, some sites don't feed their RSS well so full webpage fixes it.

Reeder¹ is my go-to. It's not free but it's gorgeous, functional and feels very much like a native app.

In my case, I use NetNewsWire at desktop and Feeder for Android. In general, works well.

Have a lot of RSS readers through the web, some of in the web, other destkops, etc. You can see which ones fills better for you.
