Re: Used both
Setting up Teams and used Skype to contact a new user to answer a few questions. They had a poor internet connection (not yet on fibre) and Skype was unusable, sound and picture breaking up. Switched to phone to finish the session and then tried to connect with their new Teams set-up - sound and vision rock solid. OK, it was a weekend and Teams bandwidth probably less pressured, but the improvement was from totally unusable to "perfect".
Teams is available free for registered charities and non-profits - one licence I got last month now reads trial expiry 20th June 2853 - I don't think I'll bother writing down renewal instructions.
Using Zoom as well for another organisation - good for conferencing and screen sharing, as was GoToMeeting. Teams has some way to go to catch up with those - but it is streets ahead as a single install in these lockdown times.
