My company mainly uses Skype for Business to do meeting calls. Sometimes people will have trouble connecting, but it's never been a problem for me. We have Microsoft Teams too, but we rarely use it. We've also tried Zoom, which is okay, but I don't understand the hype for it. It just seems like another version of Skype to me.
Personally I'm happy using Skype and probably won't be switching to another platform unless instructed to by my company.
