Like

Mattermost enables me to create unlimited communication channels in one spot. Additionally, Mattermost supports large file sharing and has a robust backend integration capability.

Unavailability of built-in video conferencing capabilities forces me to integrate MM with external web conferencing platforms.

I think other competitors give you more usage chances, such as the possibility to plan and host calls in the platform, and the chance to use an integrated sharepoint

Dislike

I slightly dislike that Mattermost requires an external web conferencing application integration to conduct video calls.
