I like Reeder for iPhone/Pad, and tried the recent beta of this. As a Mac app, it seems to have an "overtly custom" UI, which although clearly skillfully put together, just doesn't appeal to me in look or feel. Though the keyboard shortcuts and add-on services were impressively configurable.
The UI seems very iOS-like to me. I wouldn't go so far as to say it feels out of place on my Mac though. I kind of wish they made a mail client. I really like the dynamic-three column view and controls.
Would you like to expound on why it doesn't appeal to you? I would recommend using the application as your main RSS reader for some period of time before making that assessment.
