Jack Tramiel himself, in multiple interviews, would always compare his computers to his competitors, especially Apple (the company Jack almost bought when the two Steves were still in the garage). Jack continue to make those comparisons even when he later moved to Atari, basically emphasizing how much less expensive his machines were than the Macintosh, or most any competitor, emphasizing that when the machine is that low cost, and yet offer so much similar functionality, the other differences don’t matter much. Consumers mostly agreed with that as per the fact they bought Jack’s machines in the millions! You can see Jack do the Mac to Atari comparison in the video interview posted by

Most of us here are computer savvy, but some may be surprised to learn that Jack Tramiel really was not. He was a cutthroat businessman, first and foremost.
My position is, whether or not one wishes to accept the comparison of Apples to Oranges, good sound is good sound. Bad sound is bad sound. Arguments like “you gotta understand the eight bit architecture and time period“ are valid things to say to geeks focused on tech details, but they don’t negate the fact that good sound is good and bad sound is bad sound. That’s the only point I’m really trying to make on this topic.
As such, anyone mulling the purchase of a C64U will be pleased with the sound. That remains true even though the Mac had superior voice synthesis. You play a lot more background music in games than speech.
