Microsoft Teams vs Slack
Microsoft Teams and Slack are the two dominant team collaboration platforms. Teams is better for organisations already invested in Microsoft 365, offering seamless integration with Office apps, SharePoint, and video conferencing. Slack is better for tech companies that value developer integrations and a clean UX.

Tech companies prefer Slack for its developer integrations, better API, cleaner UX, and stronger developer community. Teams is preferred in enterprise environments already using Microsoft 365.
