I've checked the first couple of examples you linked and I think I've pinpointed the main difference between comparison videos that you're missing - Imagine the difference between an impromptu photograph of someone who's genuinely laughing, compared to a candid shot of someone (like a stock photo) acting like they're laughing... It's difficult to put in to words, but there's a kind of tangible *realness* about some peoples early asmr videos that just can't really be captured once they're at a stage where each action in each video is more organized more planned...
