We have been using Mattermost happily for 4 months give or take.

Our use case is basic chat features with some integrations for a team of around 40.

We run it in a t2.small instance along with another tool. I only had to manually restart it once, which is fine by me.

A postgres backend and S3 storage is most welcome and makes it very simple to manage.

My only complaint would be that the config file is not included in the postgres database so you need a separate routine for its backup. (If anyone from Mattermost reads this, please just include it in the database)

It could also handle importing multiple emojis for us Hipchat castaways.
