    Twist is more organized and less intrusive and distracting than Slack. Its interface is very nice, the app is easy to use, and it's available on all the major platforms, so for me, it's the best alternative to Slack, Hangouts and Microsoft Teams.

    Topics (the killer feature that's made Slack frustrating), excellent, clean design, very easy to onboard, integrations, channels, messaging, etc.

    Nextcloud Talk, like most of Nextcloud, is very heavyweight. So if you don't have a very good server, it's going to be very slow (for me it was around 10 seconds to send a single message)

    Same user-friendliness of Slack, but running on the decentralized/federated XMPP network. No longer give your private/confidential data to a third-party.
