Jerboa. I like what it has going on coming from RIF, comment navigation is pretty good, but it's still very buggy (often fails to refresh though that might be related to my instance more than the app, also could do with more graceful error handling) and missing a few key settings I'd like to see implemented - show instance name next to user/community names, disable left swipe to go back to post list (which I trigger on accident all the time). Hopefully the dev continues to work on it and smooth out some rough edges.
