I think more people would understand what you mean if you asked for community recommendations (or space recommendations if you want to use the Matrix-specific term). What Discord calls a "server" is not a server in any normal sense of the word, so it's going to confuse people who aren't Discord regulars, especially when we're talking about a different network that has actual servers and self-hosting support.
It doesn't matter which server you are on;You can join any Matrix rooms. Additionally, you can bridge your important Discord announcements or chats using t2bot.io .
