An issue with mattermost is that some useful features are behind a paywall, like group calls.

I’d go with nextcloud since all their features are included regardless of if you pay or not

They bundle teams with o365. The cost to integrate another messaging client is more than simply adding Teams to your already expensive bundle.

Gsuite workflow is terrible. You can’t copy paste files in drive because fuck you.

Gmail chat takes forever to load. And when it loads, it defaults to search contact. So if in the meantime, you pressed the contact you want already because it takes 5 seconds to load, it goes back to the search contact.

You need to have 5 different tabs to work within the ecosystem.

Google docs is dogshit. At this point, I prefer markdown with a latex converter over Google docs.

No desktop clients for their services.

The Gdrive shared with me vs your drive is terrible.
