I only use Teams for meetings and the calendar, and the occasional chat during a meeting. I find it totally fine and I don't really think about it much one way or the other. For reference I have a 2021 M1 Max with 64 GB.
Probably all managers and engineers working on Teams have similar copious amounts of memory and powerful CPUs on their devices and hardly use their own product. That would explain a lot
It honestly wasn't much different on my 2018 i5 Mini with 32 GB.
Maybe what sucks here is the experience of running it on Windows. Or maybe it sucks for large meetings? But I never have Teams meetings with > 40 people at this company.
