Quest for a good RSS Reader

I have always been searching for a good RSS reader for the Mac. My criteria for selection:

• Free
• Offline content
  
• No sign-ups, no logins
  
• I don't want Google to learn about what I'm reading
• Good looks
• No annoying ads

For the longest time, NetNewsWire's free version fit my needs. Recently, NNW has become annoying. Overlaid ads, greed and excessively frequent changes and updates (there's almost one every week) killed NNW's appeal. I don't care for Google Reader integration. I don't care for Google Reader, period.

I then switched over to NewsFire. It looks great. It is simple. But it lacked in many features. What killed NewsFire for me was its inability to pull in older content, even if it is on the site's feed. And there are no advanced settings.

NewsFire gave way to Vienna. I still prefer the fonts and styling of NNW and NewsFire, but Vienna does a very good job in meeting my criteria and keeping the ad banners away.
