I use Reeder too, backed by Fever. With what happened to Google Reader, the fact that Fever is self-hosted and can never go away is a big advantage for me.
I have a license for Fever, but it lost its sparkle for me due to slower sync. I could fall back to it if needed, but I use FeedBin right now.
The period between when Reeder lost Google Reader and when it gained new sync options temporarily killed RSS for me, as every other app I tested just made me wish for Reeder. It's one of my favorite apps of all time.
I am hoping that the work that was put in to make Reeder backend agnostic would be sufficient to survive another RSS aggregation service extinction event.
Of the applications I pay for on my Mac, Reeder is my favorite, with 1Password close second.
