I’m partial to the early Beatles up to the mid-1960s Rubber Soul/Revolver period, which in my opinion was their artistic peak. Starting with “Sgt Pepper”, they went downhill from there. Still a better band than most but they definitely lost something after “Revolver” that they never regained. Up to that point, they were the greatest pop/rock group that ever existed. And they really did change everything (culture-wise).

"And they really did change everything (culture-wise)."

I think they changed things musically, for sure, but they weren't the leaders of the cultural shift. The Stones and other bands, and non musicians, got there first, and The Beatles eventually joined in. Because of their enormous fame, they sometimes got credit for stuff - musical and social - that others had done first or at about the same time.
