I must be an unique snowflake, because I switched jobs around March 2020, and the new place used Teams exclusively, and... it was good. Not stellar, but good for the standards of software in this decade. Better than Slack, anyway. There were some weird glitches happening couple times a year, but nothing major.
So either I'm incredibly lucky, or - my going hypothesis - Teams actually does work quite well, if you deploy it along with SharePoint, Exchange, and other Microsoft products it integrates with.
