Ask HN: A comprehensive guide to choosing a messaging app for a community?

It's that time again when we need to pick a messaging app for a new community and yet again, the options are too many. Is there someone who maintains an up-to-date comparison table for messaging apps like Slack, Discord, Spectrum, MatterMost, Zulip, Matrix/Riot, Telegram, Rocket.chat, Microsoft Teams, Google Chat, Flock, Cliq, Keybase, Threema for Work... I'm pretty sure the list would be at least 5X of this.
