MSFT Teams -- my condolences.
I use slack, zoom, and discord for a mix of school and personal use, and appreciate what each of these offer, but wouldn’t wish to switch off of Teams for work. I do wish you could message yourself on Teams like slack. That’s a nice quick reference utility.
Why do you offer condolences for MS Teams though?
However, the product is really rough around the edges and lacks the quality you'd find in other products (well, the other product, but there are also open source alternatives* that are worth looking at as well imo).
