Help Foo choose an IM for building discussion group 😇 (Patreon)

If I were to choose one of the following to form a group chat with friends, which one would you be most comfortable with?

Discord

• Pros: Looks like it's more popular and has integration with Patreon, so it may be easy to arrange pledges exclusive channels. 
• Cons: Except I didn't use it much for the previous 😂

Telegram:

• Pros: I used to be very accustomed to using it. 
• Cons: It might be necessary to have several groups to organize different topics. As well as other friends who are not using it may not be comfortable with it.

Matrix (Element is the most popular software based on it.): 

• Pros: It is easy not to trigger interruptions because of a single large company. When encryption is configured correctly, it can improve security and privacy. 
• Cons: Fewer people seem to be using it than Telegram
