They're the GOAT. Some artists I've listened to have come close, but imo none have a discography as varied, consistent, boundary pushing across the board, both accessible and experimental as The Beatles. Besides that few, if any, artists have had an impact on the world even remotely close to The Beatles, who single-handedly ushered in a revolution in the music industry and culture in general. They're kinda like The Godfather. Of course many people don't have it as their #1 favorite movie (it's also not my #1 movie), but most of us can accept its status as the GOAT for it's undeniable quality in all aspects.
