Pro Groups
It's possible to send messages to multiple people at once. Either by setting up a group or by selecting a bunch of people individually. Groups can also be muted if they get too noisy.
Pro Messages self-destruct after they've been viewed
Once a message has been viewed, it gets deleted from Snapchat's servers. Thus, unless a person chooses to save the message manually (a notification will be sent if a user decides to take a screenshot), there will be no trace of it left. It enables a bit more consequence-free, in-the-moment kind of communication to occur.
Pro Generates a contact list
Once the account setup process is complete, Mirage generates a list of people from your contacts that you are most likely interested in sending messages via Mirage.
Pro Interface designed for getting things done quickly
Tap a contact to take a picture, tap and hold a contact to record video. Tapping the screen will allow you to add text to photos and videos just taken. Swiping the screen changes what camera is used. Swiping from the side allows sending text and voice messages. Voice messages are recorded the same way videos are by tapping and holding on a contact just from a different view.
Cons
Con No web interface (yet)
Currently there is no web interface to send message using your computer. Project leads have teased screen shots of the web interface.
Con Few users currently
Allo was just released in September, 2016 and it doesn't have a very large following yet. We haven't yet seen how popular it's going to be.
Con Exclusive
If your contacts aren't on Allo it is worthless, and no one is on Allo. Tried it after Hangouts fail, discarded it within days.
Con History deletes on sign in
If you uninstall the app or migrate to a new phone your messages history is deleted. This, despite the fact that Google keeps a copy of your messages permanently for data crunching.
Con Single device
Part of reliably saying if one saw your message, and having it tied to a phone number, is that you cannot have the same Allo account on two phones.
Con Buggy
Messages get lost users have trouble getting their codes to log in and has trouble actually finding the users contacts.
