Minstrel

I didn't forget that. It's fairly well-established that the Beach Boys and Beatles consistently pushed each other to be better. McCartney said that Pet Sounds pushed the Beatles back into the studio for what ended up becoming Sgt. Pepper's, because Pet Sounds set a new standard. And certainly Brian Wilson was inspired to try and create better, by work of the Beatles.

I think the Beatles made great music. They're one of my favourite bands (even if I don't listen to them much anymore, since their music is so ubiquitous). I just don't think they were one of the most experimental bands of the time. Experimenting with looping, time signatures, etc, were not pioneered by them. To their credit, they were willing to pick up new techniques and try to change their sound and they did it incredibly well, but I don't think they revolutionized anything. I do think Brian Wilson's production techniques revolutionized how pop and rock music was made. Though, of course, he built upon Phil Spector.
