Our Verdict
Choose Slack if you prioritize a best-in-class messaging experience, work with many external partners, use diverse third-party tools, or want a communication platform that stays focused on chat and channels without feature bloat.
Choose Microsoft Teams if your organization already uses Microsoft 365, you need built-in video conferencing and file collaboration, want to consolidate tools into one platform, or need enterprise-grade security and compliance that integrates with Azure AD.
