His best album is 'McCartney' and , whadya know!, it's the one with the best front cover, back cover, photographs, graphic design and typography.
Also, and this is often lost over the years with all the CD reissues, the LP records in the 50s, 60s and very early 1970s were much better made than after the early 1970s due to the recycling of vinyl after the Oil Crisis, and the general naffness of printing/design as the decade lumbered on.
And 'McCartney' still incorporates that sheen of plastic on the cover that made The Beatles LPs so attractive, and certainly seems to have been lost by the time of 'Wild Life' in 1971.
