I recently recorded about ten interviews for a webinar produced by a client. I could have used Zoom or Skype but thought that I could get better quality by producing the videos with vMix Call. vMix is a live streaming software package and Call is the feature that lets you connect with others via RTC for recording conferences:

vMix delivered excellent quality and usability. This video shows how to use vMix call.
