Quick verdict
Choosing between Zoom (500M+ installs) and Microsoft Teams (500M+ installs) usually comes down to workflow, not raw feature counts.
Zoom, built by Zoom Video Communications, Inc., focuses on hd video meetings, webinars, whiteboards and team chat. Microsoft Teams from Microsoft Corporation instead leans into chat, meet and collaborate on office files in one workspace. The two products are similar enough that comparing them feature-by-feature, rather than spec-by-spec, gives you a clearer answer.
