Well I can remember and fully recognise 17/17 characters that Oda has on that colour spread.
For Kubo, I recognise 5/9 characters and can only really remember the names of 4/9.
The One Piece colour spread looks better to me. Far livelier scene, better and more varied outfits, better colour palette, superior designs. It looks more aesthetically pleasing. The Kubo spread looks dull and lifeless in comparison.
