As a teacher experienced in both these platforms I would like to share my insights on this comparison.
1. Extensions – Most features are not built into the application and have to be installed as a browser extension to chrome.
2. Breakout Rooms – Supervising the participants in zoom breakout rooms is a complicated and tedious process. Besides needing many screens and workarounds, it also requires to have high-speed connectivity which may be an issue if you have five users online at a given time and place.
3. While zoom is about as easy to use as gmeet it is not browser-based and therefore a hassle sometimes.
4. Gmeet so far has not come up with a mute all button and muting 100 participants is a big deal.
5. The free version of gmeet will not let you record a meeting, whereas zoom gives the recording capabilities.
6. Meeting durations – The free version of zoom has a limit of 45 minutes after which your call will end. Gmeet has unlimited duration.

The icing on the cake is perhaps your delivery style, speaking skills and mechanism of connecting to a live virtual audience. Keeping your style unique and engaging as well as adequately interacting with participants has no substitute. A discussion for another day.
