Feedly, I choose Feedly because of the positive reviews for the app, as I read mainly using my phone. So far I am liking it. Easy to use, synced Google Reader info right over. Love the layout and font better than Google Reader so that is a plus.
Now let's see if Google Reader really goes away. I began using bloglines many moons ago and they announced a close date and failed to close due to user requests...that's when I switched to Google Reader.
