Honestly, the farther you get away from it, it's clearer to me that John was the most inspired artist, especially lyrically, but his music composition is rather over simplistic, or maybe even a little unskilled. Paul was the most competent music composer, but his concepts were very pop, & not as deep. He did after all write what is now widely considered the most hated Christmas song ever lol
That's why Lennon/McCartney gravitated to making the best songwriting team, that complementing of one another
Ringo was the best personality, while going largley unrecognized for being a perfectly competent & enjoyable performer, & George was the best instrumentalist. He wrote some good stuff too, but I feel like his best compositions were directly inspired from being in the creative element The Beatles offered.
I'd actually say that about all of them. I think them all having such different areas of excellence meant they were a good mesh, that complemented each other, & also found a way to bolster each other in areas they each might not have been as good at as someone else. Once they were working apart, they no longer had that kind of counterbalance in their work. They drove each other to better their weak areas, & support their excellent ones
It's the same reason I'm grateful they also happened to have their friendly rivalry with Brian Wilson & The Beach Boys. The existence of that external adversary IMHO made both groups strive to achieve better & more inspired creations. So too with the internal dynamics of the Beatles.
Mick Jagger is on record calling The Beatles, 'The Four-Headed Monster.'
Individually they were quite good, but together they were unparalleled.
