We pay for Slack for the screenshare feature but not for any integrations. I like the simplicity and snapiness of Slack's chat and screen share compared to other modern platforms. No lag, minimal stupid animations, and cross platform compatibility. Easy enough to write integrations against too.

'Threads' feature is annoying and I hate it when people try to use it. Code formatting is nice.

Federation with MS Teams could be nice so I don't have to launch Teams whenever the one off meeting happens but that will never happen.

Shrugs It's good enough.
