Slack vs Microsoft Teams

Slack is often the preferred standalone chat platform for its interface and app ecosystem. Microsoft Teams is usually the default for organizations already paying for Microsoft 365, where it is effectively bundled. If your company runs on Microsoft 365, start with Teams; if you are choosing a best-of-breed chat hub and budget allows, evaluate Slack.
