The only place I've ever worked that used Teams treated it as a replacement for Lync/Skype for Business. We just DM'd each other sporadically and nothing really got posted in public channels. Everything was also set to auto-delete after 60 days so it couldn't be searched as a long-term knowledge repository (why this was done is left as an exercise to the reader). Teams as an app is generally mediocre but my company's implementation was garbage; Slack is an order of magnitude better in every respect.
