We went through a similar change for our internal communications.
In the past, we were using the free Slack subscription, but found there was too many limitations for the free version. Since we already pay for M365 licenses, it made more sense to switch over to Teams.
The bonuses we have found is that Teams has replaced our GoToMeeting software, as well as provide nice features like "email to channel" and other things.
There was some "teething" issues with the changeover, mainly with just getting used to the GUI and how to use it, but these have all but been forgotten about now.
I agree with the other reports of Teams being stable, I can't recall the last time there was a fault with the software itself.
