I have that constant feeling of missing something with google inbox, with sufficient keyboard short cut expertise, on a good day I could handle 300-400 mails in gmail, and feel productive. With Inbox, many of those mails are well hidden, and even if I can safely discard whole bunch of mail at the same time, there were couple of instance that made me go back to gmail.
