Mattermost idealistically might be competitive with Slack, but right now it isn't. Most people who only care about usability and features will choose Slack over Mattermost. Just use the apps for a couple days and the differences and issues between them are clear as day. I'd like Mattermost to succeed. But it needs to do a lot of catching up still.
