My experience with Digg reader is that it is still subpar, though better than Feedly. Specifically, I've seen it miss updates on some feeds (sometimes for days at a time), and it frequently "forgets" that I've looked at items and shows them as new again (seems to be a UI glitch). It also frequently shows feeds as having unread items but no items are actually unread (seems to be a server-side glitch, resolved by marking read in bulk).
Digg Reader is still the best I've found, but still feels like a notable step down from the reliability and consistency of Google Reader.
