TBF I have less experience with Dynamics than the others, but yes they are all excellent.

I include Teams in that. I don't think there is another app on the market that does what Teams does. Integrated video conferencing, messaging, and file sharing in one place. All free with the office package my team already use and fully integrated with Azure AD for sso. I use it all day with zero problems. I honestly can't see why anyone would use anything else
