content: Obviously the comparison would be with Slack. Some things are better in Teams some things better in Slack. Not being able to chat to self and a personal as well as assignable remind commands are two things I really miss. Integration with OneNote and Team wikis are great features. There is a bit of a learning curve as you get used to where things are and not being able to setup private channels threw me for a loop but the same thing can be accomplished by setting up specific teams.
