A big difference is the source material. The Beatles didn’t have a very wide exposure to music, but they had a very deep one. They grew up in an era when American R&B was literally revolutionizing the musical culture of Britain. And in crossing the pond and being selected by disc jockeys with rabid audiences, there was a distillation that took place. So the Beatles in their youth were not just exposed to some American music - they were listening to the absolute best R&B ever created, and way more of it than most white kids in America were getting. It’s fascinating that this sort of convergence of all the most incredible aspects of American roots music had to take place outside of the US, create genres like Skiffle (unheard of in America), and spit out kids like Paul McCartney who would go on to “invade” America with a sound that was familiar to US ears and yet something else entirely. The magic still happens - see Amy Winehouse, the Scoundrels - but these are sort of like subsequent moon landings, despite being amazing in their own right.
