The big differentiator was the software. Where the Amiga had Caligari and the Video Toaster, the Mac had Illustrator and Pagemaker (such as they were), and desktop publishing was a much easier fire to light than desktop video at the time.

YouTube would have been a very, very different experience on a Hayes SmartModem.
