Zoom Wins
Zoom takes it overall (9/10 vs 7/10), but Mattermost is still the sharper pick for regulated industries, government, defense, and orgs requiring on-premises data.
Zoom's standout strength: Best-in-class video quality and reliability across bandwidth conditions. Its biggest drawback (free tier limited to 40-minute meetings with 3+ participants) is easier to live with than Mattermost's (requires infrastructure and IT support to self-host). Mattermost isn't out of the running though — its own standout strength is self-hosted deployment, full data control. If you fit the profile of regulated industries, government, defense, and orgs requiring on-premises data, that alone can flip the decision.
