How does Google’s Inbox stack up against some competition?

Inbox is certainly a decent offering from Google, but there are a lot of other good email apps out there.  So how does it stack up against some competition?  I primarily use Mailbox on iOS and on my Mac, so I thought I’d do a quick run down of the key features – Mailbox v. Inbox.

I’d say that as things stand Mailbox is more functional and efficient.  In the long run Inbox will become a stronger contender but it is almost certain that no other email providers will be supported!  What are your thoughts?  Add them here or on Google+.
