Slack is not a good example for this headline. Loads of chat applications are much better than Slack. Slack sucks. Slack is chosen by business people, who heard about it from their business friends and ignore input from their tech team.

Examples:

Discord - but terrible data policy as well, but at least works fluently without long load times and they managed to use webrtc in 2020, which Slack still sucjs at and gives you BS about using Firefox and limits It for the free account. Ridiculous.

Zulip Chat - Much better chat functionality and conversation model. Can be self hosted.

Anything with a proper Markdown parser, not something that sucks as much as whatever Slack is using. Oh well, but it could be worse looks at Atlassian Confluence.

Anything that does not heat up 4 Cores at 100% at startup for an inapproprIate amount of time.

Anything respecting your privacy.
