video calls and audio calls- which is better - Skype for business or teams?
Don't think it matters, it really depends more on where you are in your adoption journey, the underlying technology and infrastructure is the same, at least going forward I believe so the experience should be much the same.
"To complement the Teams capability as a persistent chat board where informal, real-time conversations take place, Teams also provides a calling and meeting experience built on the next generation cloud-based infrastructure that is also used by Skype and Skype for Business."

Personally, across several Office 365 tenants, I find that the quality of video and audio calls is better with Teams. This isn't altogether surprising as Teams uses the next generation audio/video platform, but the experience has been consistent for several months now. Glitches do happen with Teams, as with all software... so your mileage might vary.
