Best conferencing app we've used
My organisation has recently rolled out Teams, and the biggest improvement I've noticed over other communication platforms is a far better audio/video conferencing experience*, particularly when taking with China (I visit frequently for work). In the past, Skype or Skype for Business has been unusably bad, so we used regular phones. Nowadays WeChat seems to be the most reliable system by a nose, but Teams calls have less delay and better audio quality, so you can actually have a conversation instead of the usual garbled and stuttering meetings. Usable screen sharing is a welcome bonus.
* I realise this is surprisng, given that Teams is basically just a branding wrapper for Skype for Business. However, MS have definitely done something better, maybe just giving the system an larger amount of bandwidth & resources until they've got everyone hooked.
