Discord or discourse for a community?

I run a screencast for developers, and I have a private telegram group for paid customers. Now that we are reaching 50 ppl on the telegram group some members suggested that we move it to discord.

I was actually considering discourse, because I will be able to leverage user-generated content for SEO, and it allows for more elaborate conversations (i.e potentially bring more value to customers and me). I would only allow paid customers to post messages on it, but the posts would be public. And I would keep the telegram for simple conversations on mobile, and attracting attention for a conversation on the discourse forum.

I have seen some people recommending to use both discord and discourse at the same time, but I am afraid it will be too much, and people won't know where to focus.

Thoughts?
