A and B examples are convincingly "human". It is complete nonsense to say otherwise. The AI versions are simply giving the music a kind of commercial streamline production treatment; treatment that many listeners need to accept the music as viable. Some will fight brutally to hide this need here. No offense, but both a and b are thoroughly cliché. The AI is not sucking away some grand uniqueness of expression here. I have heard both raw and produced countless times. Humans are generative AIs already -- fighting machines that do it is ironic and dishonest. Sure the AI process may be robbing some of the "honesty" of the performance. But you guys aren't unique like Daniel Johnston when you are unfiltered so I don't see a problem with either version. The studio is a place of magic and sonic makeup. If you want to wear makeup, go for it.
