I send code snippets, quote sections of linked documents, and provide in-line links pretty often, kind of like here on Lemmy. Slack isn’t as nice as Markdown, but it’s good enough, whereas Teams is a complete pain in in the butt and it completely butchers code blocks. That said, I’m a team lead, so I fairly frequently post about recent releases, security issues, or give cliff notes of recent meetings, so formatting for me matters quite a bit.

And for calls, we have multiple logical groups of people, such as:

• development teams
• team leads (for all teams)
• groups by location
• groups by role (developers, QA, etc)
• release groups - may be part of a team, multiple teams, or parts of multiple teams
• automated alerts when prod has an issue

And we have ad-hoc group chats where just a handful of people need to be involved, but they don’t fit cleanly into one of the established groups above (e.g. project manager wants to know a rough estimate for an upcoming project).

Teams works fine, but I find it annoying to use.
