Is Slack Worth It in 2026? Honest Review vs Microsoft Teams and Zoom

Slack is worth it in 2026 if your team values a best-in-class messaging experience and you're not locked into the Microsoft 365 ecosystem — its search, integrations (800+), and workflow automations are the most polished of any team messaging tool. Slack Pro ($7.25/user/month) and Business+ ($12.50/user/month) give small-to-mid teams unlimited message history and more storage. Microsoft Teams is worth it if your company already pays for Microsoft 365 (Teams is included at no extra cost) — the Excel, Word, SharePoint, and Outlook integrations are native and deep. For video-first teams or companies that prioritize meetings over async messaging, Zoom Team Chat is the better hub. The decision comes down to ecosystem: Slack wins standalone, Teams wins inside Microsoft 365.
