Ranked in these QuestionsQuestion Ranking
Pros
Pro Officially supported by Slack
Pro Native notifications
Pro Slack on a web browser can interact with local app
Pro Very fast due to not being based on Eletron
It provides a traditional compact desktop interface designed for power users. It's not built on top of web browser technology: it responds quickly to input, sips gently from computer resources, and gets out of your way. It does voice chat, too.
Pro Compact app which uses less than 20 MB of ram
Very low RAM Usage compared to official slack app
Pro Tab layout allows for better organization of conversations
The addition of tabs along the top makes it much easier to hold several conversations at once.
Cons
Con Utilizes more resources as it is built on Electron
The official Slack client is built on top of the Electron framework and is quite a bit more resource-intensive than some of the alternative clients.
Con Still in beta
Con Not FOSS
Ripcord is shareware. They have a trial AppImage available, but you have to pay 20 dollars for the full version. Also, you can't recompile it or easily package -- which means it can't be managed by your distro's package manager.
Con Doesn't run properly under Wayland
Con Text selection does not work
Only whole messages can be copied.
Con Unable to identify who sent emoji responses
There is no way to tell who responded with emojis on messages. Sometimes this is actually really important.
