Paul conceived the idea of Pepper but I think Johns tracks stand out more ie A Day In Th Life and LSD
Pepper was sort of Paul's album but I agree John's "Lucy" and his segments of "Day In The Life" stand out.... in a similar way you could argue that A Hard Day's Night was very much John's album, yet Paul's "Can't Buy Me Love" "And I Love Her" and "Things We Said Today" more than hold their own.
I always think of the albums in terms of who dominated, like Paul dominated Let It Be and Abbey Rd, John dominated Hard Days Night, Rubber Soul, Paul dominated Revolver etc etc
I think The White Album, Let It Be and to a large extent Abbey Road are essentially "Paul-centric" but I'd have to disagree with you about Revolver nimrod. That was firmly John's & George's for me, those jangly spangly guitars on things like She Said She Said, I'm Only Sleeping and Taxman are the hallmark sound of Revolver... Paul is kind of hanging behind and out of step from the others - some of his tracks here are brilliant but somehow more old fashioned, less cool / cutting edge and - dare I say it - somehow less "Revolver-ish" (if that makes sense!) than the more exploratory Lennon/Harrison stuff which seems to share a more mutually "with it" LSD/psychedelic vibe at this point.
