I recently read this book of transcripts of interviews with the Beatles - it was brilliant! All 4 of them were witty and hilarious, actually, real team effort. (Especially John, though!) Maybe it's one of those " there are two kinds of people in this world" dichotomous choices (cat-person/dog-person? Beatles/Stones?), and so your perception of frontmanhood comes down to whether you prefer John songs or Paul songs. So I say John!

Good question - I think Paul was the more natural showman but John might have been the stronger creative force - Most point to the beginning of the end as John/Yoko so he seemed to be the glue that held them together.
