They are all equally crap. I'm convinced the people designing collaboration tools don't have to use them on a daily basis.

The plague that is currently infesting our software industry is "Promo-Driven Culture". Employees are incentivized to get a promotion, not to make life better for anyone, except for their manager's promotion.

I’m sure the people who designed Teams and Meet use their own products on a daily basis. And if those are crap, what’s a better alternative?

It is funny, that even a Slack Huddle, something that's not even the core of Slack's function, is better than anything one gets with MS Teams. MS Teams is so laughably bad, I think I have never used a worse chat/voice chat/video chat program. Probably not even Skype in its single core days was worse, even though it ate one third of my single core CPU, just to have a call back then.

What is it that is bad about it these days?

In the early Skype days, that tradeoff made sense. Internet speeds across the globe were far from fast so they spent more CPU cycles on compression so they could save on bandwidth.

Zoom + Slack

Do they? Didn’t Microsoft force all its employees back to the office?

That doesn’t sound like they have faith in Teams themselves.

I use Teams every day and it can’t even do threading in channels properly. The spellchecker is unreliable and even copy and paste is occasionally patchy.

It is not a good product. I’d switch to Slack given the choice.

Teams is used in the Teams org that develops it in Microsoft yes. Source: I work on Teams free/consumer.

Not to say that the developers working on it are satisfied with it..

IME the call quality varies quite widely between video calling software. And being able to reliably hear and be heard with reasonable latency is pretty important!

Equally?

Definitely not.

Maybe it can be argued that it depends on how you use it, but meet is so far and away better for video calls and screen sharing, its not even funny.

Jitsi is also an incredible improvement, and it is self hostable and free.

Teams is likely the worst software that a company will force on all its employees- with that in mind, I guess some people can get stockholm syndrome? Some people who only jump from MSFT shops literally don’t know that there’s anything better. They went from Communicator to Lync to Skype for Business and now to Teams- and Teams is better than those just about.

It seems you have had the fortune to not have had to suffered through jabber

Oh, I did… I quite liked it actually. :)

When it comes to Teams, unfortunately we do. It's actually used across Microsoft in general. A company of this size requires Teams even if just for the sake of keeping up with security and compliance.
