Reader itself has problems of this sort, but Byline is significantly worse. So lately I've been trying Reeder. I wrote this quick review for the app store ...
Bad news first. It crashes more than it should, but not more than Byline. Secondly it needs a manual, and it desperately needs a "reset" button to wipe its local store and force a reload from Google Reader. Thirdly it get its sync state confused, but no more than Byline. Lastly it doesn't precache the source pages, so Byline has a big edge there. There's no support for creating a Google Reader "Note" status update (Byline doesn't either).
Now the good news. The under-documented UI is elegant -- once you figure it out. (Programmers raised on games think life is a role playing adventure.) Readability is excellent. There's an option to open source pages in Instapaper Mobilizer - a vast improvement over Google Mobilizer. Services and configurability is excellent. Performance is great, so stability is now a bigger issue. It shows Following (Byline doesn't) - but here it gets counts wrong.
Bottom line - definitely worth the money, currently the best of breed, room for stability and synchronization improvements and, for the love of Binary, please add a reset option.I think Reeder is a better app than Byline -- for the moment. It's not perfect though. If the developer doesn't fix a few bugs soon I'll take a look at Mobile RSS next.

Update 9/30/10: No contest. Reeder is much better. There are bugs (Followed count), and crashes, and I miss the original page pre-caching -- but it's still the clear winner.
