So, I went through the platform and here's what I like:

* Quick calls (meetings without the need to schedule them - just share the links, similar to google meets.
* Scheduled meetings
* And tons of options for delivering great Webinars.
* The docs. They put a lot of effort into them and this means you can answer any questions about how to achieve something just by searching for it in the docs.

So, the great thing is, as someone else has already mentioned, the platform seems to cover a loooot of use cases, which is great for us. Less platforms - less overhead.

Here's what we need for the product to REALLY work for us. The team seems to be on top of at least some of these, judging by comments here:

* We absolutely need Tevent to be in German
* Quick call would be even better with an option to reset (or even automatically reset) the chat etc. for a given links. So we could just reuse the link for meetings with different people with a clean slate (such as emptying chat history etc.)
* Create recurring events, eg. for a weekly course with the same class
