Ensemble by Pyxis. Web site in Japanese but has English translation available. Supports RSS and Atom.
Feed by Keith Anderson. "There are a lot of RSS readers for Mac OS X out there, and Apple even added RSS capabilities directly to Safari in Tiger (10.4) - so why did I write this? Because all of the existing (Free) RSS readers are approaching the problem from the wrong side.
I treat my RSS feeds more like email than anything else, and the current crop of RSS reader is more a hybrid between iTunes and a web browser. I wrote Feed to address this issue."
