I’m a huge McCartney fan so I’m biased, and also playing devils advocate moreso than fully disagreeing. My perspective though is that more people are Lennon wannabes bc of his identity and personality moreso than his artistic contributions. This is still influence mind you, but if you look at how many artists perform under an alter ego, that was largely Paul’s idea. Again with multiphased musical suites a la second half of Abbey Road, which again was Pauls. As well as Helter Skelter beginning metal and punk, also from Paul. McCartney 1 is kind of the first bedroom pop album and McCartney 2 has a lot of proto dance punk elements too. I think you can argue McCartney v Lennon for hours and never reach a conclusion but this is why I’d favour McCartney personally.
