I must admit that I like QuickTime for macOS. I can do a screen recording and submit it to YouTube for others to see. On one occasion, I discovered that some Hackintosh can’t screen record with QuickTime but was able to find a solution by trial and error.
The reason when I like to utilize QuickTime for macOS is for a feature that has sadly been dropped in macOS Catalina. That feature is to be able to enable pause in QuickTime for macOS so that you can take a break, save time cutting unnecessary footage in post-production or stop from recording sensitive information.
