Skype vs Zoho Cliq

We chose RocketChat over other communications suites like Cliq or Slack mainly because we can self-host it on our own infrastructure. Since we have quite some projects going on which demand that we stay in touch with a lot of different stakeholders, pricing was an issue, too. With RocketChat, we have a huge set of features basically for free, RC offers apps for all major devices and systems and overall, we're very happy with it. The only downside is the limited amount of apps and integrations, but we can make due with what we have available.

Hi, I am helping teachers in my kid's schools to set up distance learning and wanted to see what is better between Webex, Zoom, and Skype (although only putting this one in as most parents probably have it). The children are 8-9, so they won't be using it on their own and the parents have no experience using Webex or Zoom.

The main use will be for the teacher to explain what they will be covering in the week and enable some social interaction between the kids.

I need to be easy to use for about 20-25 people.

Thanks for your advice, Lisa
