Comparison of Clouthub Meets and Zoom Meetings

Has anyone used Clouthub Meets and how does it's functionality (like annotate and whiteboard tools, etc.) compare to Zoom?  I have a client who is convinced zoom is stealing our personal information and selling it and wants me to use Clouthub instead, but I can't find where it has the feature we need for meetings.  Any help is appreciated?

cheers,
